The problem
Requirements stay unclear. Vendor claims go unverified. Exceptions have no owner or expiry date. Projects proceed because deadlines are visible and residual risk is not.
Organisations should proceed when evidence exists, not when confidence merely feels high.
Brutal honesty makes the truth usable
A defensible decision does not guarantee that nothing will go wrong. It shows the organisation considered the context, relied on appropriate evidence, understood the trade-offs and assigned accountability.
See how we work →Know what supports the decision. Verified evidence is kept apart from analysis, assumptions and matters still to confirm.
Risk is weighed against your environment, obligations, priorities, capability and tolerance for disruption.
Material risks, actions, exceptions and deadlines have named owners, and responsibility does not fall between you, us and your vendors.
Each recommendation says what happens next, who does it and what evidence will show it is closed.
“I feel like I've got a great cybersecurity team when I've got Cliffside. They leave no stone unturned.”
Figures reported by DeltaPAE.
“Because of their support and honest advice, our security posture is much better than what it was six months back.”
“…a report that was packed with actionable items and in priority order. This made it super clear to us what we needed to work on.”
“Tested more than the default OWASP Top 10 / basic testing, created custom checks specifically for LLMs. Recommend without hesitation”
