Senior identity expertise, without the overhead
One accountable architect, 14+ years of Fortune 500 experience, and a focus on outcomes that hold up under audit.
Why Rivitan exists
Rivitan exists for a simple reason: most enterprises are running identity infrastructure that grew organically over a decade or more — and it shows. Duplicate accounts, over-privileged admins, fragile federation, and access nobody can fully account for.
Over 14+ years working inside Fortune 500 environments, I have seen the same patterns repeat across retail, finance, healthcare, and manufacturing. The good news is that they are solvable with the right architecture, a disciplined approach, and a focus on outcomes that hold up under scrutiny.
I started Rivitan to give organizations access to that senior, hands-on expertise directly — without the overhead, hand-offs, and junior staffing of a large firm. When you engage Rivitan, you work with the architect who does the work.
“When you engage Rivitan, you work with the architect who does the work — not a rotating cast of juniors.”

Principles behind every engagement
Outcomes over jargon
Security work only matters if it reduces real risk and survives an audit. Every engagement is measured by outcomes a CISO can defend, not buzzwords.
Leave teams stronger
Good consulting transfers knowledge. Documentation, runbooks, and training mean your team owns the result long after the engagement ends.
Senior, hands-on, accountable
You work directly with the architect doing the work — not a rotating cast of juniors. One accountable point of contact from first call to handoff.
Security without disruption
Phased rollouts, pilot groups, and documented rollback plans mean we improve your posture without breaking what your business depends on.
