Prove trust. Stay ready.

Security proof that holds up, from security questionnaires to investor diligence.

An enterprise prospect just sent a 300-question security review. You need a pentest for your upcoming compliance audit. Kobalt runs the pentest, completes the questionnaire, and hands you evidence that stands up to an auditor, a buyer, or an investor, so the proof is ready before the next deal asks for it.

Proof, not paper

Proof that holds up, not paper that checks a box

Plenty of firms will sell you a report dated within 12 months. That satisfies the box on the questionnaire and tells your engineers nothing. Take a penetration test: the point is to find what needs fixing before your customers, your auditors, or a real attacker does.

How it works

From scoping call to a deliverable your buyers accept

Whether it's a pentest, a tabletop, or an application security review, every Kobalt engagement runs the same way: a fixed scope, a clear deliverable, and no open-ended retainer. Most run for a few weeks, and we move as fast as you need.

1

Scoping call

We agree on the scope, the deliverable, and the timeline, then give you a fixed quote. No prep required, and no scoping-before-scoping.

2

The engagement

We run the test, exercise, or review you booked. If something critical surfaces, you hear about it the same day, not in the final report.

3

Findings report

Every finding carries a severity rating, a clear description, reproduction steps where they apply, and specific remediation your team can act on. Not generic advice.

4

Debrief call

We walk your team through the findings, answer questions, and make sure the plan to close them is clear before you start.

5

Re-check

We validate that the fixes hold, so you can prove it to a buyer or auditor. Pentest retests run at 20% of the original within 3 months.

Proof that goes above and beyond.

The pentesters were amazing, they went above and beyond with regard to testing.

Common Questions

Security proof questions, answered straight

How do we answer a security questionnaire quickly?
Start from what your security program already does, not from a blank page. If you're on one of our programs, we complete the questionnaire with you at no extra cost, drawing on your policies, your pentest report, and your evidence. Higher volumes (four or five a month) are scoped separately. The fastest answer is the one you prepared before the questionnaire arrived, which is the whole point of keeping proof current.
What do investors ask for in security due diligence?
Usually a current penetration test report, your security policies, evidence that controls actually operate, and proof you can respond to an incident. A data room that already holds those shortens diligence and protects your valuation, because the deal doesn't pause while you scramble to produce them. We keep that evidence ready before anyone asks.
How much does a penetration test cost?
Grey Box and Black Box Small engagements start at $3,000, and pricing is published so you know the cost before you get on a call. Most web application tests fall in that range through medium scope; White Box testing for mature applications is custom and typically starts around $25,000. A retest of remediated findings is 20% of the original.
Do we need an incident response plan?
Yes, if you want to pass most audits or qualify for cyber insurance. An incident response plan documents who does what when you're breached, across six phases from prepare through lessons learned. It's a baseline requirement for SOC 2, ISO 27001, and HIPAA, and insurers increasingly reject applications without one. A tabletop exercise then tests whether the plan actually works under pressure.
Do we need a pentest for SOC 2 or ISO 27001?
Yes. An annual penetration test is required for SOC 2, ISO 27001, and most frameworks, and enterprise security reviews often ask for a report dated within the last 12 months. Most clients run their first test during SOC 2 readiness, then repeat it on the same annual schedule as their audit. If you're pursuing a framework, our compliance team runs that program alongside the test.
What is a tabletop exercise, and do we need one?
It's a role-play exercise that walks your leadership through a realistic breach scenario to test decisions under pressure, then debriefs with the gaps it surfaced. Many frameworks expect one, and cyber insurers increasingly ask for evidence you've run it. If you have an incident response plan but have never tested it, a tabletop is how you find out whether it actually works.
Can you test our AI or LLM features?
Yes. We test against the OWASP Top 10 for LLM Applications, covering prompt injection, jailbreaking, sensitive information disclosure, and insecure output handling. It runs standalone or as an add-on module to an application pentest, so the AI in your product gets the same scrutiny as the rest of it. Buyers have started asking how you secure it, and this is the evidence that answers them.
