Artificial intelligence is rapidly evolving beyond tools that simply generate answers. A new wave of AI systems can now make decisions and take actions inside enterprise environments.
This emerging model is known as Agentic AI.
Unlike generative AI systems that respond to prompts, agentic AI agents can interact with applications, trigger workflows, analyse data, and act autonomously to achieve defined goals. As organisations begin exploring these capabilities, the opportunities are significant. But so are the security and governance challenges.
In the latest episode of the Cyber Insights Podcast, Ronan Murray and Ian Finlayson speak with security leader and author Josh Woodruff about what agentic AI means for enterprise environments and why organisations must start thinking about security before these systems are deployed at scale.
What Is Agentic AI?
Most people associate artificial intelligence with tools like ChatGPT. These systems fall into the category of generative AI, where a model produces responses based on prompts.
Agentic AI operates differently.
An AI agent is given a goal and a set of tools. It can then reason through tasks and take actions repeatedly until the goal is achieved.
These actions may include:
calling APIs
interacting with enterprise applications
updating systems or records
triggering operational workflows
analysing internal data to make decisions
In simple terms, agentic AI moves beyond answering questions to performing work inside systems.
One analogy shared during the podcast captures the concept well.
Agentic AI is like a junior employee with system access.
It can carry out tasks independently, but it still requires oversight, clear permissions, and governance.
Why Agentic AI Changes Enterprise Security
When AI begins operating inside enterprise systems, the security model changes.
Traditional applications follow predefined workflows. AI agents, however, can reason about information and decide which actions to take next.
This means organisations must start thinking about AI agents as identities operating within their environment.
Like any other identity, AI systems require:
authentication and identity management
clearly defined permissions
monitoring of behaviour
segmentation of systems and data
governance over what they are allowed to access or change
Without these controls, organisations risk granting autonomous systems access that may expose sensitive data or critical infrastructure.
Prompt Injection. The Emerging AI Security Risk
One of the most significant risks associated with agentic AI is prompt injection.
AI agents rely heavily on the data they consume to determine their next actions. If that data contains malicious instructions, the AI system may unknowingly follow them.
Examples could include:
malicious instructions embedded in documents
manipulated data sources
compromised emails or tickets
poisoned datasets designed to influence AI behaviour
Because agentic AI operates at machine speed, the consequences of incorrect actions can occur far more quickly than traditional human-driven processes.
This makes data governance and monitoring critical for organisations planning to deploy AI agents in production environments.
Why Zero Trust Matters for AI Security
As AI systems gain the ability to take action across enterprise environments, many of the principles behind Zero Trust architecture become increasingly important.
Zero Trust assumes that no user, device, or workload should be trusted by default. Instead, access must be continuously verified and limited to only what is required.
When applied to AI systems, this means:
every AI agent should have a unique identity
access should follow least-privilege principles
systems and data should be segmented
behaviour should be continuously monitored
Applying Zero Trust principles helps ensure that AI agents operate within tightly controlled boundaries, reducing the potential impact if something goes wrong.
Governing Autonomous AI Systems
The biggest risk with agentic AI is not always malicious activity. Often, it is unintended autonomy.
Organisations may deploy AI systems without fully understanding the capabilities they have granted. Without clear governance, these systems can make decisions or take actions that were never anticipated.
This is why many security experts recommend introducing AI agents gradually.
Start with narrow use cases and limited access. Monitor behaviour closely and expand capabilities only as the system proves reliable.
In practice, this means treating AI agents exactly like new employees entering the organisation. They should start with restricted permissions and gain trust over time.
Preparing for the Next Phase of Enterprise AI
Agentic AI represents a significant shift in how artificial intelligence will be used inside organisations. As AI moves from experimentation into operational systems, security and governance must evolve alongside it.
Organisations that introduce strong identity controls, monitoring, and Zero Trust principles early will be far better positioned to adopt these technologies safely.
If you're interested in exploring these concepts in more depth, Josh Woodruff’s book Agentic AI and Zero Trust, co-authored with Michelle Savage, provides a practical framework for governing and securing autonomous AI systems in enterprise environments.
The book introduces the Agentic Trust Framework, a simple set of principles designed to help organisations safely deploy AI agents while maintaining strong identity, access, and security controls.
If your organisation is exploring how AI adoption will impact security architecture, networking, and governance, it's important that security evolves alongside these technologies.
If your organisation is exploring how AI systems will interact with enterprise infrastructure, ensuring your network and security architecture is ready is essential.
The Edge7 Networks team works with you to design secure networking and cybersecurity frameworks that support emerging technologies while maintaining strong security controls.
In the latest episode of the Cyber Insights Podcast, Ronan Murray and Ian Finlayson explore these challenges in detail with security leader and author Josh Woodruff, discussing both the opportunities and the risks of autonomous AI systems.
