Have a question?

Who is SentinelSec for?

Seed to Series B startups that sell, or are about to sell, to larger companies. You need a security function before you can justify hiring one, and your first enterprise customer will ask for proof. We give you that function from day one and scale it as you raise.

What's included in a monthly plan?

Foundation ($10,000/mo) puts the security basics in place for seed-stage teams. Growth ($20,000/mo) adds SOC 2 readiness, an annual penetration test, security questionnaire support, privacy compliance readiness and monthly security reviews. Scale adds vCISO leadership, continuous penetration testing, AI security assessments, vendor risk management, incident response readiness and board-level reporting. See Pricing.

Can you just run a penetration test?

Yes. Penetration tests, red team engagements, AI security assessments and M&A due diligence are available as standalone projects. Every finding comes with reproduction steps, the fix and a retest once you have shipped it, plus a report you can share with customers.

A security questionnaire is blocking a deal. Can you help?

Yes. We answer CAIQ, SIG and custom vendor questionnaires accurately and consistently, so a follow-up call does not unravel them. We can also set up a Trust Center so prospects can review your security posture themselves.

How do you get us SOC 2 ready?

We start with a gap assessment against the SOC 2 Trust Services Criteria, then build the policies, controls and evidence your auditor will test. We take you to Type I or Type II, whichever your customer requires. See Enterprise Readiness.

What does AI red teaming cover?

LLM applications, AI agents and RAG pipelines: prompt injection, data leakage, tool and agent misuse, and unsafe outputs. We threat-model, test, reproduce, remediate and retest. See AI Red Teaming.

What happens in the free assessment?

A working session, not a sales pitch. We look at your actual environment and tell you what a customer, auditor or attacker would find first. You leave with a prioritized roadmap you keep, whether or not we work together.

How do I get started?

Book a free assessment, or email hello@sentinelsec.ai and we will reply the same business day.
