B2B SAAS & SOFTWARE

Application Security and AI Security for AI-Powered SaaS

SaaS application security with AI focus covers AI red-teaming (testing AI features against prompt injection, jailbreaking, and adversarial inputs), traditional penetration testing with AI awareness, multi-tenant security audits, and the security engineering that production AI requires. BearPlex builds these systems with the rigor SaaS production requires: automated and manual security testing, multi-tenant isolation verification, AI-specific threat modeling.

Why Application Security & Penetration Testing matters in B2B SaaS & Software

SaaS AI features create new security attack surfaces: prompt injection in AI agents, jailbreaking of customer-facing AI, multi-tenant data leakage through AI features, supply chain attacks on AI components. Traditional application security doesn't cover these threats. AI-aware security is now a required capability for SaaS organizations shipping AI features. The security work that matters in SaaS is integrated with engineering velocity, not a blocker.

What we've learned deploying application security & penetration testing in b2b saas & software

From the field

Three patterns from BearPlex SaaS appsec engagements: (1) AI security is application security with new attack surfaces; traditional appsec methodology applies but must extend to cover prompt injection, jailbreaking, AI supply chain; (2) Multi-tenant AI security failures are high-severity: cross-tenant leakage through AI features is the same severity as traditional cross-tenant leakage; (3) Continuous testing matters more than point-in-time audits: AI features change rapidly and security must be continuous.

REGULATORY CONSIDERATIONS

B2B SaaS & Software compliance considerations

SaaS appsec must respect customer compliance posture: SOC 2 Type II requirements; GDPR / CCPA; sector-specific frameworks per the customer base; OWASP LLM Top 10 emerging as expected framework for AI security. For consumer-facing AI features, AI disclosure and safety requirements increasingly apply.

SOC 2 Type II
Required for enterprise customers; impacts how AI systems handle customer data
GDPR
EU customer data residency and right-to-explanation for AI decisions
CCPA / CPRA
California consumer privacy: applies if SaaS has any California users
ISO 27001
Information security management system: common procurement requirement
FAQ

Common questions

Systematic adversarial testing of AI features: prompt injection, jailbreaking, attempts to extract system prompts, attempts to bypass safety controls. Required for production AI deployment to identify vulnerabilities before adversaries do.

Traditional appsec covers web app, infrastructure, identity, network. AI security adds prompt injection, jailbreaking, training data attacks, model supply chain, multi-tenant AI isolation. Many techniques transfer; some are AI-specific.

Yes: common engagement type. Adversarial testing of cross-tenant isolation in AI features (retrieval, generation, action-taking). Cross-tenant leakage through AI features is high-severity; we test for it explicitly.

$80K-$300K for an 8-14 week engagement depending on scope, AI feature surface, and continuous testing requirements.

Yes: increasingly common engagement scope. OWASP LLM Top 10 is becoming the expected framework for AI security review. We structure audits against these categories.

Primarily Lahore, Pakistan (HQ) with team members in Tokyo and globally distributed.

Both. Point-in-time audits for new feature launches or compliance requirements. Continuous testing infrastructure for ongoing AI security as features evolve. Most production AI clients benefit from continuous testing because AI features change too fast for point-in-time audits to keep up.
