The cybersecurity industry is quietly undergoing the same transition as the rest of tech—AI is no longer a feature, it is the system itself.

Cloud security has effectively been absorbed into the baseline; it no longer differentiates companies because every vendor now offers it.
AI introduces entirely new vulnerabilities—data poisoning, model manipulation and extraction of proprietary information—expanding the attack surface beyond traditional infrastructure.
Enterprises are embedding AI into core workflows and deploying autonomous agents, multiplying both productivity gains and security risks.
A new category of companies is emerging, focused specifically on securing models, training pipelines and AI behavior.

The shift is structural. Security is moving from protecting systems to protecting cognition—models, decisions and data flows. In that sense, AI security is less a sub-sector and more a redefinition of the perimeter.
