Terry Lewis

Founder & CEO of RoboShadow

Terry Lewis is the founder and CEO of RoboShadow. He started the company on a simple conviction: cybersecurity has been made far more expensive and complicated than it needs to be, and the teams that reduce risk fastest are the ones that close the loop between finding a weakness and actually fixing it — not the ones that produce the longest reports.

Under Terry’s direction, RoboShadow brings external attack-surface scanning, internal and agent-based device scanning, third-party CVE detection and CIS hardening for Windows and Microsoft 365 into a single platform, with remediation handled automatically through Cyber Heal and AI AutoFix. The mission behind all of it never changes: demystify cybersecurity for SMBs, MSPs and the enterprise by cutting the cost and the complexity at every step.

He writes about vulnerability management, exploit-aware prioritisation (CVSS, EPSS and the CISA KEV catalogue), configuration hardening, and how small teams can run a continuous security programme without a dedicated department.

From the author

Find it, fix it, prove it.

A short list of the right fixes, actioned automatically and verified, beats the longest report. That is what vulnerability management is for — and it is what we built RoboShadow to do in one place.
