AI Security: How to Protect AI-Powered Workflows

AI is becoming part of everyday business operations, from assistants that summarize information to agents that can take action across connected systems. That creates a new security challenge: organizations aren’t only protecting applications, identities, networks, and data anymore. They also need to secure the AI models, agents, workflows, and permissions operating across them.

Many of the fundamentals of cybersecurity still apply, but AI introduces additional risks. Sensitive information can enter prompts or outputs, models can be manipulated, agents can be given excessive permissions, and automated actions can increase the impact of a security failure.

AI security brings these risks into one discipline. This guide covers what AI security means, the most important risks to understand, how organizations can secure AI systems and agents, and where AI itself can strengthen cybersecurity.

What is AI security?

AI security is the practice of protecting AI systems, the data they use, the applications and workflows they connect to, and the people and organizations that rely on them. It covers everything from controlling access to models and sensitive data to protecting against malicious inputs, monitoring AI activity, and limiting what autonomous systems can do.

As AI becomes more deeply connected to business operations, the security boundary expands. An AI assistant that only generates text presents one level of risk. An AI agent that can retrieve company data, update records, communicate with customers, or trigger workflows requires additional controls around identity, permissions, actions, and oversight.

Security for AI vs. AI for security

AI security is sometimes used to describe two related but different practices. Understanding the distinction matters because organizations increasingly need to address both.

Security for AI means protecting AI systems themselves. This includes securing models, training and business data, prompts, agents, integrations, and the infrastructure surrounding them. Controls are designed to prevent threats such as unauthorized access, data leakage, prompt injection, model manipulation, and unintended agent actions.

AI for security means applying AI to cybersecurity work. Security teams can use AI to analyze large volumes of activity, identify unusual behavior, prioritize alerts, summarize incidents, and automate repetitive parts of investigation and response.

The two increasingly overlap. As organizations use more AI, they need stronger controls around the AI itself. At the same time, AI can help security teams monitor increasingly complex environments.

This guide focuses primarily on the first challenge: securing AI systems and agentic workflows. Later, we’ll also look at how AI can strengthen cybersecurity operations.

Why AI security matters for every team

AI security isn’t just IT’s job; it’s everyone’s. When AI powers sales pipelines, marketing campaigns, HR workflows, and customer service, every department has a stake in AI security. The team using an AI agent to score leads has as much at stake as the team that set it up.

Protecting customer data and intellectual property

AI systems often process sensitive customer data (contact info, purchase history, communication records, deal values) and proprietary business intelligence, such as pricing strategies, competitive analyses, and internal playbooks. Without proper safeguards, AI can accidentally expose this data through outputs, logs, or third-party integrations.

Here’s what that looks like:

An AI assistant that summarizes sales calls might inadvertently include confidential deal terms in a shared report visible to the broader team
An AI agent researching competitors might store proprietary strategy documents in an unsecured location or include sensitive internal data in its analysis output
A lead-scoring agent with overly broad data access might reference financial information it was never intended to see

Enabling confident AI adoption across departments

Fear is one of the biggest barriers to AI adoption. Teams worry about data privacy, unintended actions, and loss of control. The gap between AI excitement and actual usage is huge. Even inside tech companies, real agentic AI usage is in the single digits. There’s excitement, FOMO, and uncertainty, but most teams don’t know where to start.

Strong AI security practices remove these barriers and help teams adopt AI with confidence. Security supports adoption rather than blocking it. Teams that can see exactly what an AI agent did, verify that it only accessed authorized data, and know that high-impact decisions require human approval are far more likely to integrate AI into their daily workflows.

Meeting compliance and regulatory requirements

AI introduces new compliance obligations beyond traditional data protection. Regulations like the EU AI Act, GDPR’s implications for automated decision-making, and industry-specific requirements (HIPAA for healthcare, SOC 2 for SaaS providers) now extend to how organizations deploy and govern AI systems. If your AI agent makes decisions that affect customers, such as scoring leads, routing support tickets, or prioritizing outreach, those decisions may fall under regulatory scrutiny.

Six key pillars of AI security

AI security can’t be reduced to a single control. Protecting the model itself won’t prevent sensitive data exposure if permissions are too broad, and strong access controls won’t help teams identify suspicious behavior if AI activity isn’t monitored.

A stronger approach uses multiple layers of protection across the AI lifecycle. These six pillars cover the areas organizations need to consider together, from access and data protection to transparency, monitoring, and human oversight.

1. Data security and privacy

AI systems depend on data, and that data is often the most vulnerable point in the entire AI lifecycle. Data security in the AI context means protecting training data from tampering, ensuring customer data processed by AI remains encrypted and access-controlled, and preventing AI systems from retaining or leaking sensitive information.

Encryption at rest and in transit: All data flowing to and from AI systems should be encrypted using industry-standard protocols
Data minimization: AI systems should access only the minimum data necessary to perform their functions
Retention policies: Organizations should define how long AI systems can store data and enforce automatic deletion
Ownership rights: Organizations should retain full ownership of data provided to AI systems and any content those systems generate

2. Access control and identity management

Access control determines who and what can interact with AI systems and the data they touch.

AI agents make access control particularly important because they may be able to retrieve information or take actions across multiple connected systems. The broader those permissions are, the greater the potential impact of compromised credentials, malicious instructions, configuration errors, or unexpected agent behavior.

This is where the principle of least privilege provides a useful foundation. Each user, application, and AI agent should receive only the minimum access necessary to perform its intended function. For an AI agent, that might mean restricting which data it can retrieve, which systems it can interact with, and which actions it can perform without additional approval.

Role-based permissions: Assign AI access based on team roles and responsibilities
Granular scoping: Limit AI integrations to specific workspaces, boards, or datasets rather than granting blanket access to the entire account
Authentication protocols: Use secure authentication methods like OAuth for all AI connections

3. Threat modeling and adversarial resilience

Threat modeling is the practice of systematically identifying how AI systems could be attacked or misused. Adversarial resilience refers to an AI system’s ability to withstand deliberate attempts to manipulate its behavior.

Prompt injection: Attackers craft specific inputs designed to override an AI system’s instructions
Data poisoning: Attackers corrupt the data used to train or fine-tune AI models
Model extraction: Attackers systematically query an AI system to reverse-engineer its behavior
Evasion attacks: Attackers craft inputs specifically designed to bypass AI detection systems

4. Monitor AI activity and maintain audit trails

AI security doesn’t end when a model or agent is deployed. Teams need visibility into how systems behave in real workflows, particularly when AI has access to sensitive information or permission to take actions.

Logging AI activity creates a record teams can use to investigate unexpected behavior, identify unusual patterns, and understand what happened during a security incident. For agentic systems, useful audit information can include which agent acted, what resources it accessed, which actions it attempted or completed, and where human approval occurred.

Monitoring should also be tied to a response process. Define which behaviors or thresholds require investigation, who owns that investigation, and what happens when suspicious or unintended activity is detected. Visibility is most valuable when it leads to action.

5. Governance and lifecycle management

AI governance covers the policies, processes, and accountability structures that guide how AI is deployed, maintained, and retired across an organization.

Designated ownership: Every AI system has an identified owner responsible for its security, performance, and compliance
Documented usage policies: Written policies that define how AI may and may not be used across the organization
Regular reviews: Periodic assessments of all AI systems to ensure they still meet security and performance standards
Decommissioning procedures: Defined processes for retiring AI systems that are no longer needed

6. Transparency and explainability

Transparency means being able to see what AI systems are doing and why. Explainability means being able to understand and communicate the reasoning behind AI decisions.

Audit trails: Every AI action is logged with enough detail to reconstruct the decision chain
Decision logs: AI systems maintain human-readable records of their reasoning, not just their actions
Human-readable explanations: AI outputs include context that helps team members evaluate whether the action was appropriate

AI security risks and how to mitigate them

Data poisoning and training data manipulation

Data poisoning occurs when attackers deliberately corrupt the data used to train or fine-tune AI models, causing the AI to produce biased, inaccurate, or harmful outputs.

Validate and audit training data sources before use
Implement data integrity checks that detect unauthorized modifications
Use diverse, verified data sources to reduce single points of failure
Monitor AI outputs for unexpected shifts in accuracy or behavior

Prompt injection and input manipulation attacks

Prompt injection is a technique in which attackers craft inputs designed to override an AI system’s instructions and cause it to perform unintended actions.

Input validation and sanitization: Filter and validate all inputs before they reach AI systems
Output filtering: Review AI outputs before they’re executed or displayed
Sandboxed execution environments: Run AI systems in isolated environments.
Separation of instructions and data: Design AI systems so that system instructions and user inputs are processed through distinct channels

Model theft and intellectual property exposure

AI models themselves can be valuable intellectual property. Attackers might attempt to steal or reverse-engineer models by systematically querying them.

Rate limiting and query monitoring: Restrict the volume and pattern of queries to AI systems
Output controls: Implement filters that prevent AI systems from including sensitive internal information in their responses
Access segmentation: Separate AI systems that handle internal-only data from those that interact with external users
Watermarking and fingerprinting: Apply techniques to identify whether your model has been copied

AI supply chain vulnerabilities

Most organizations rely on third-party AI models, APIs, integrations, and plugins. Each of these represents a link in the AI supply chain, and each link is a potential vulnerability.

Vet third-party AI providers thoroughly
Review integration permissions regularly
Maintain an inventory of all AI dependencies
Establish contractual protections

Shadow AI and ungoverned AI usage

Shadow AI occurs when employees use AI applications or integrations that haven’t been approved, vetted, or secured by the organization.

Create an approved AI catalog
Make sanctioned AI adoption easy and fast
Conduct regular audits to discover unauthorized AI usage
Educate teams on the risks

How AI strengthens cybersecurity operations

Securing AI is only one side of the relationship between AI and cybersecurity. AI can also give security teams additional ways to detect, understand, and respond to threats.

Security operations generate enormous volumes of information, and manually reviewing every event or alert isn’t realistic. AI can help analyze that activity at scale, identify patterns and anomalies, prioritize signals that deserve attention, and summarize information for security professionals. Used appropriately, it can reduce repetitive analysis while keeping people focused on decisions that require security expertise and judgment.

Then keep the existing use cases underneath, but bulk up any that are currently only one or two sentences.

Automated threat detection and hunting

AI can analyze vast volumes of network traffic, user behavior, and system logs to identify threats that human analysts might miss. AI-powered detection identifies subtle patterns and anomalies that don’t match any known rule.

Fraud detection and anomaly identification

AI excels at identifying patterns that deviate from normal behavior, including unusual transaction amounts, login attempts from unexpected locations, or sudden changes in user activity.

Identity and access management

AI enhances identity verification by continuously analyzing user behavior patterns to detect compromised accounts or unauthorized access attempts.

Phishing detection and prevention

AI can analyze email content, sender behavior, and communication patterns to identify phishing attempts with greater accuracy than rule-based filters.

AI security best practices: how to protect AI systems and agents

No single security measure can protect an AI system on its own. Effective AI security uses layers of controls across identities, data, models, integrations, agent behavior, and the workflows surrounding them.

The appropriate controls will depend on what the AI can access and what it’s allowed to do. A tool that summarizes public information doesn’t require the same safeguards as an agent with access to customer records and permission to update business systems. The greater the potential impact of an AI action, the stronger the controls around it should be.

Use the following practices to build those protections into AI systems from development through deployment and ongoing use.

Apply least-privilege access to AI integrations

When connecting AI assistants or agents to a work platform, administrators should scope access to only the specific workspaces, boards, or data sets the AI needs.

Maintain audit trails for every AI action

Every time an AI system creates an item, updates a status, or generates a report, that action should be logged with a timestamp and context.

Keep people in the loop for high-impact decisions

For decisions that significantly affect customers, revenue, or operations, AI should recommend or draft them, but a person should review and approve them before execution.

Review and update AI security controls regularly

AI capabilities evolve rapidly, and security controls need to keep pace. Quarterly reviews of AI permissions and governance policies are recommended.

Securing AI agents and autonomous workflows

Why AI agents need dedicated security controls

AI agents can operate autonomously, executing multi-step workflows and making decisions without continuous human input. This autonomy amplifies both their value and their risk.

Assigning identity and permissions to AI agents

AI agents should be treated like team members. Each agent should have a defined identity, explicit permissions, and documented responsibilities.

Monitoring agent activity across departments

Centralized monitoring that provides visibility into agent activity across all departments is essential to ensure data sensitivity levels are respected.

Set clear guardrails for AI behavior

Guardrails are predefined boundaries that limit what an agent can do, how much it can do, and when it must pause for human approval.

Permissions determine what an AI system can access. Guardrails define what it should be allowed to do with that access.

For AI agents in particular, teams should establish boundaries around permitted actions, restricted actions, and situations that require human approval. An agent might be allowed to retrieve information, summarize a record, or categorize a request independently while requiring approval before deleting data, changing permissions, communicating externally, or completing another high-impact action.

Guardrails should reflect the risk of the workflow rather than applying the same level of autonomy everywhere. Low-risk, reversible tasks may be suitable for greater automation, while decisions involving sensitive information, financial impact, employee outcomes, or customer access may require stronger human oversight.

Teams should also test those boundaries before deploying agents into live workflows. Simulation, sandbox environments, and staged rollouts can help identify unexpected behavior while the consequences are still contained.

Secure AI agents according to what they can do

AI agents require particular attention because they can move beyond generating information and take actions inside business systems. That changes the potential impact of a security failure.

Start by mapping each agent’s scope: what information it can access, which applications it can interact with, which actions it can perform, and whether those actions are reversible. An agent that summarizes project updates presents a different risk profile from one that can modify customer records, approve requests, or trigger external communications.

Apply permissions and guardrails accordingly. Limit access to what the agent genuinely needs, require human approval for higher-risk actions, log agent activity, and periodically review whether its permissions still match its role. As agent capabilities change, their security boundaries should change with them.

AI security governance, compliance, and key frameworks

Technical controls determine what an AI system can do. Governance establishes what it should be allowed to do, who is accountable for its use, and how the organization manages AI risk as systems evolve.

That makes AI security governance a cross-functional responsibility. Security and IT teams understand technical risk, but legal, compliance, privacy, business leaders, and the teams actually deploying AI also influence how systems should be used.

A practical governance framework should establish ownership, classify AI use cases by risk, define approval requirements, document acceptable use, and set expectations for testing, monitoring, incident response, and periodic review. The objective isn’t to slow AI adoption down. It’s to give organizations a repeatable way to decide where automation is appropriate and where stronger controls are required.

NIST AI risk management framework

The NIST AI RMF provides a structured approach to identifying, assessing, and mitigating AI risks through four core functions: Govern, Map, Measure, and Manage.

The EU AI Act and global AI regulations

The EU AI Act establishes a legal framework for AI deployment using a risk-based classification system (Unacceptable, High, Limited, and Minimal risk).

Industry certifications that support AI security

Key certifications include SOC 2 Type II, ISO/IEC 27001, ISO/IEC 27701, and HIPAA.

How to evaluate AI platforms for secure adoption

Keep humans involved in high-impact decisions

Automation doesn’t have to mean removing people from the process entirely. Human-in-the-loop controls allow organizations to determine where AI can operate independently and where a person needs to review, approve, or override an action.

The appropriate level of oversight depends on the consequences of getting something wrong. Automatically categorizing an internal request may require little intervention. An AI-generated decision affecting access, finances, employment, security privileges, or sensitive customer information deserves considerably more scrutiny.

Human reviewers also need meaningful authority. A workflow isn’t genuinely human-in-the-loop if someone technically approves an action but lacks the information, time, or ability to challenge the AI’s recommendation. Effective oversight gives reviewers enough context to understand the proposed action and the authority to stop or change it.

Put secure AI agents into practice with monday AI Workspace

AI security principles become much more concrete once agents start working inside real business processes. At that point, organizations need more than a policy describing how AI should behave. They need controls that determine what agents can access, what they’re allowed to do, and where people remain involved.

With monday agents, teams can build AI agents into workflows while maintaining visibility and control over how they operate.

Control what agents can access and do

Agent security starts with scope. Teams can define the data and workflows available to an agent and establish boundaries around the actions it can take, helping prevent unnecessary access from becoming unnecessary risk.

Keep human oversight where it matters

Not every action needs the same level of autonomy. Teams can keep people involved in higher-impact workflows and use simulation to review agent behavior before relying on it in live processes.

Create greater visibility into agent activity

When AI becomes part of operational work, teams need to understand what it is doing alongside human activity. Centralizing work and agent activity in monday AI Workspace gives teams greater visibility into how AI is being used and makes oversight part of the workflow rather than a separate security exercise.

Build AI governance into everyday work

Security, IT, legal, and business teams all have a role in responsible AI adoption. monday AI Workspace gives those stakeholders a shared environment for managing workflows, ownership, permissions, and oversight as agent use expands.

The result isn’t AI without risk. No platform can provide that. It’s a more controlled way to introduce agentic AI, with boundaries around what agents can do and visibility for the people responsible for governing them.

Build AI security into the way AI works

AI security becomes more important as AI moves from answering questions to participating directly in business processes. Models and agents can access information, connect systems, and increasingly take action, which means organizations need security controls designed for that level of capability.

The fundamentals are layered: protect data, restrict access, set clear guardrails, monitor activity, keep humans involved in consequential decisions, and establish governance that evolves alongside AI use.

The goal isn’t to prevent organizations from using AI. It’s to make sure increasing automation doesn’t mean decreasing control. When security is built into AI systems and workflows from the start, teams can adopt new capabilities while maintaining the visibility, accountability, and oversight they need.
