The Key to Agentic Security is not to Secure the Agent

The Key to Agentic Security is not to Secure the Agent

Oct 28, 2026 By Dr. Peter Vincent, CTO, Outerlimit In SecuritySenses
In September 2024, OpenAI announced o1 and updates to its Assistants API. Looking back, this marked a shift in how AI systems would be used. These systems were no longer just generating answers. They were starting to connect with tools and affect the world directly. Tool use had previously been possible, but it was clunky and unreliable. Now, it is becoming a native capability. Yet this new ability has arrived before the underlying models have become trustworthy. Real-world capability is being handed to systems whose outputs cannot always be relied upon.

7 Modern Car Safety Features to Compare Before Making a Purchase

7 Modern Car Safety Features to Compare Before Making a Purchase

Oct 28, 2026 By SecuritySenses In SecuritySenses
Buying a car involves more than comparing prices and comfort. Modern cars have safety technologies that help drivers spot dangers and avoid crashes. However, two cars that seem similar may perform differently due to their sensors and software. Understanding these differences can help you make better choices. Some technologies actively assist in dangerous situations, while others only provide warnings. Comparing independently tested safety features can show you which systems offer real protection and which might have hidden limitations you won't notice during a short test drive.

ClickFix: How a fake CAPTCHA becomes a malware delivery mechanism

Oct 27, 2026 By Judin Joan Soundarya In ManageEngine
CAPTCHAs are designed to distinguish humans from automated systems. A user types distorted letters or clicks a few crosswalks, and in doing so proves there is a human behind the keyboard rather than a script. The whole idea rests on one assumption: A human, unlike a bot, will pause and think for a moment before acting. ClickFix takes that assumption and turns it into the attack itself. The fake verification screen does not ask the user to prove they are human by thinking.

Every AI Agent Creates Security Debt. Most Organizations Aren't Tracking It.

Oct 27, 2026 By Exabeam In Exabeam
Technical debt accumulates when organizations prioritize immediate speed and defer the architectural work that keeps systems dependable. Most engineering leaders know how that story ends. The shortcuts that made the first release possible eventually slow down every release after it. The agentic enterprise is creating a security equivalent.

How to Block Sensitive Data in AI Prompts at the Endpoint

Oct 27, 2026 By Cyberhaven In Cyberhaven
A data loss prevention (DLP) team writes a rule to keep customer records out of ChatGPT. The rule catches an uploaded spreadsheet but misses the same records pasted into a prompt, because no file transfer occurred. The team adds text pattern matching to close the gap, and the rule starts flagging harmless prompts that happen to contain a name and a number. Both failures share one cause. The rule judges what the text looks like and cannot see where it came from.
