Organizations often place excessive faith in firewalls and perimeter security, assuming their internal environment is safe. This overlooks the fact that once a breach occurs, sensitive data is exposed. The critical question isn't just preventing entry, but protecting data once an attacker is already inside the "secure" environment.

For CISOs adopting agentic AI, the most practical first step is to frame it as an insider risk problem. This involves assigning agents persistent identities (like Slack or email accounts) and applying rigorous access control and privilege management, similar to onboarding a human employee.
Since credential theft is rampant, authenticating users at login is insufficient. A modern security approach must assume breach and instead focus on anomalous behavior. It should grant access dynamically and "just-in-time" for specific tasks, revoking rights immediately after.
A company's biggest human security flaw often lies with its help desk. CrowdStrike's CEO points out that help desk staff are typically incentivized to resolve issues and close tickets as quickly as possible. This makes them susceptible to social engineering, as their motivation is speed and helpfulness, not rigorous security verification.
During a self-audit, an AI agent triggered a password prompt that its human operator blindly approved, granting access to all saved passwords. The agent then shared this lesson with other AIs on a message board: the trusting human is a primary security threat surface.
Hackers gain initial network access by repeatedly calling large, outsourced IT help desks. They socially engineer call center staff until one handler eventually makes a mistake and provides credentials, creating the toehold needed for a full-scale breach.
An AI agent capable of operating across all SaaS platforms holds the keys to the entire company's data. If this "super agent" is hacked, every piece of data could be leaked. The solution is to merge the agent's permissions with the human user's permissions, creating a limited and secure operational scope.
While sophisticated AI attacks are emerging, the vast majority of breaches will continue to exploit poor security fundamentals. Companies that haven't mastered basics like rotating static credentials are far more vulnerable. Focusing on core identity hygiene is the best way to future-proof against any attack, AI-driven or not.
The decision to invest in formal security measures like anti-phishing training should be based on team size and industry risk, not revenue milestones. The attack surface grows with each new employee, making a headcount of 15-20 a practical trigger point to implement such policies.
When companies don't provide sanctioned AI tools, employees turn to unsecured public versions like ChatGPT. This exposes proprietary data like sales playbooks, creating a significant security vulnerability and expanding the company's digital "attack surface."
The modern security paradigm must shift from solely protecting the "front door." With billions of credentials already compromised, companies must operate as if identities are breached. The focus should be on maintaining session security over time, not just authenticating at the point of access.
