What’s really there
Evidence from your systems and controls
ABOUT
Clarity is a security capability.
Postura helps organizations replace disconnected findings and false certainty with a defensible picture of risk.
OUR PHILOSOPHY
Security guidance should create movement.
A technically correct report can still fail if leadership cannot use it or teams cannot act on it. We bring evidence, context, and decisions together so the work leads somewhere.
THE POSTURA LENS
One shared view.
What it means for your business
Context from the people who know it best
What to do first
A clear order of action
MEET THE FOUNDER
John Diaz
Founder & Principal
John founded Postura Security after 25 years in information security—most recently as Head of Information Security and as a member of the governing body of a Gartner CISO community.
His career has spanned nearly every side of the discipline: operational security, compliance, offensive security, engineering, and architecture. That range is deliberate. Security fails differently in a factory than in a bank, and differently again in a government agency—and knowing why is what separates a finding from an answer.
He has worked with organizations including IBM, ING, American Express, Boeing, NASA, Dow Chemical, thyssenkrupp, GAP, the State of Georgia, and the Atlanta Regional Commission—environments where the stakes were real and the constraints were unforgiving.
He started Postura on a simple conviction: most organizations do not lack security data—they lack a clear, honest picture of what it means and what to do about it. Today he brings that enterprise-scale experience to small and mid-sized businesses that need senior security judgment without the overhead of a full in-house function.
