Startup Security

Your security team before you're ready to hire one.

From your first product launch to your first Fortune 500 customer, SentinelSec provides the security expertise you need to build, protect and prove your security program.

Hiring a security engineer takes six months and costs more than most seed rounds allow. We give you the coverage of a security function from day one, and scale it as you raise.

By stage

Security that matches where you actually are

The wrong move at seed is buying enterprise tooling. The wrong move at Series B is still running on spreadsheets. Here is what each stage genuinely needs.

Seed

Build the foundation

Get the basics right before they become expensive to retrofit.

  • Baseline security assessment
  • Core security policies
  • Cloud configuration review
  • Vulnerability management
  • Risk assessment
  • 12-month security roadmap
Series A

Become enterprise-ready

Your first large customer will ask for proof. Have it ready before they ask.

  • SOC 2 readiness
  • Penetration testing
  • GRC program stand-up
  • Privacy compliance
  • Security questionnaire support
  • Customer-facing Trust Center
Series B

Scale security

Security becomes a function, not a project.

  • vCISO leadership
  • Continuous testing
  • DevSecOps integration
  • Vendor risk management
  • AI security
  • Incident response readiness
Enterprise

Operate like a mature program

Board-level accountability and continuous assurance.

  • Continuous PTaaS
  • Red team engagements
  • Advanced GRC
  • Enterprise security reviews
  • Board reporting
  • Long-range security strategy

What you get that a tool subscription does not

Scanners produce findings. Security programs produce outcomes customers can verify.

Judgment, not just findings

A scanner will hand you 400 issues. We tell you which three matter this quarter and why, so your engineers ship fixes instead of triaging noise.

Evidence customers accept

Reports, policies and control documentation written to survive procurement and audit review — not internal-only checklists.

Work that fits your stack

Findings arrive as actionable tickets mapped to your repos and cloud accounts, with remediation guidance your engineers can act on directly.

A program that compounds

Each engagement builds on the last. Your posture improves measurably quarter over quarter instead of resetting with every point-in-time test.

Find out where you stand

A free assessment covering your cloud, application, policy and compliance posture — with a prioritized roadmap you keep either way.

No obligation. You keep the roadmap whether or not we work together.
