Security That Unblocks Enterprise Sales

For B2B SaaS, security is a revenue function — not just a cost center

The Stack Enterprise Buyers Actually Ask For

Every B2B SaaS company eventually hits the same wall: a Fortune 500 prospect's procurement team sends a 400-question security questionnaire, asks for your SOC 2 Type II report, demands pentest evidence, and wants to know how your AI features handle their data. Nomad's SaaS practice is built around getting you through that wall — and keeping you there as you scale from Series A to public company. SOC 2 + ISO 27001 readiness, deep technical pentesting, cloud security, AI/LLM security, and a vCISO who knows the difference between "the audit passed" and "the customer signed."

Specialization Across SaaS

From Series A through public — different stages need different programs

Pre-Seed & Seed

"Security checklist" baseline: free vCISO office hours, lightweight cloud-config review, and a security narrative for your investor deck. Light-touch and budget-aware.

Series A – B

SOC 2 Type I → Type II program, first pentest, customer-questionnaire library, and a vCISO who can sit on enterprise-prospect security calls.

Series C+ & Late-Stage

SOC 2 Type II + ISO 27001 dual-track, ongoing pentest program, red team engagement, and mature security organization build-out.

Public Companies

SEC Form 8-K Item 1.05 incident-disclosure readiness, SOX ITGC support, board-level security reporting, and acquisition-target security diligence.

AI-First Companies

OWASP Top 10 for LLM Applications, AI red team, model-isolation review, customer-data-in-training risk, and enterprise-grade AI security narratives.

Regulated-Vertical SaaS

HealthTech (HIPAA + HITRUST), FinTech (PCI + SOC 2), EdTech (FERPA), and Public-sector (FedRAMP) — multi-framework programs in a single engagement.

The Bugs and Threats Specific to SaaS

What we find on real engagements and respond to in real incidents

Multi-Tenant Isolation Failures

The bug class that has ended SaaS companies. BOLA, broken function-level authorization, IDOR across tenant boundaries, and shared-resource leakage. Our web app and API pentests include explicit cross-tenant authorization-matrix coverage.

Cloud Identity & CI/CD Compromise

Sisense, Okta, Cloudflare-Atlassian — recent SaaS breaches all originated in identity or CI/CD. Our cloud pentest practice tests IAM, GitHub Actions OIDC, secret-store hygiene, and the trust chain between your dev environments and production.

OAuth-App & Third-Party Integration Abuse

OAuth-app phishing of customer admins, malicious-integration risk in your marketplace, and over-permissive third-party SaaS-to-SaaS connections. Pretexting tests and integration-security review are increasingly enterprise-buyer asks.

AI Feature Security & Customer-Data Exposure

Prompt injection, training-data leakage, model output that exfiltrates customer data, and the customer-facing question "how do you isolate our data from your AI?" — these are now standard enterprise-buyer concerns. We help you have credible answers.

How We Engage With SaaS Companies

The "Series A Security Sprint"

90-day fixed-scope engagement covering SOC 2 Type I readiness, baseline web/API pentest, customer-questionnaire library, and ongoing vCISO support. Designed for pre-Series-A and immediate post-Series-A companies.

Continuous Compliance Program

Year-round SOC 2 Type II + ISO 27001 program with rolling evidence collection, quarterly internal audits, and ongoing pentest cadence. The off-the-shelf compliance-tool replacement.

SaaS Pentest Program

Annual web + API + cloud pentest rotation calibrated to enterprise-buyer expectations. Multi-tenant isolation testing included. Reports formatted for customer security review.

AI Feature Security Review

For SaaS companies shipping AI features: model security testing, customer-data isolation review, prompt-injection assessment, and customer-narrative coaching.

Enterprise-Deal Acceleration

Live support for enterprise-prospect security calls, vendor-questionnaire response, and the "can you talk to our procurement team?" asks that close deals.

Incident Response Retainer

1-hour-SLA IR retainer with pre-negotiated rates. Critical for SaaS — your customers' boards will ask within 24 hours whether you've activated professional IR.

SaaS Security FAQ

Probably yes — the question is which type. SOC 2 Type I (point-in-time) can be achieved by a 15-person company in 60–90 days. SOC 2 Type II (operational period) requires 3–12 months of running controls before audit. We usually recommend starting Type I as soon as enterprise prospects are asking, then transitioning to Type II for the next renewal.

For most growing SaaS companies, yes — they're a great evidence-collection layer. But they don't write your policies, design your control environment, or coach you through audit objections. We work alongside all the major automation tools and frequently set them up for clients. The tool is the system of record; we're the security program.

Yes. Our reports are formatted with an executive summary suitable for customer security teams, a technical findings section for engineering, and an attestation letter your sales team can share without exposing the technical detail. Multi-tenant isolation findings are highlighted explicitly because that's what enterprise SaaS buyers focus on.

A mature SOC 2 Type II program shares 70–80% of its controls with ISO 27001. From SOC 2 to ISO 27001 certification is typically a 4–6 month engagement — gap assessment, statement of applicability, additional documentation (Annex A controls), risk-treatment plan, internal audit, and stage-1/stage-2 certification audit coordination. We've shepherded dozens of companies through this exact path.

Three things beyond the usual SaaS stack: (1) AI security testing aligned to OWASP Top 10 for LLM Applications and MITRE ATLAS, (2) customer-data isolation review — provable separation of customer data from model training, and (3) the "AI security narrative" that enterprise buyers now ask for in security questionnaires. We've written that narrative for dozens of AI companies.

Common engagement: acquisition-diligence security support. We help you prepare the security disclosure pack, anticipate buyer-diligence questions (especially around historical incidents, vendor risk, and AI-feature data handling), and represent your security program credibly in management presentations. On the buy-side, we perform target-company diligence assessments for VC and PE firms.
