Shift Security Upstream to Eliminate Vulnerability Debt

Reactive penetration testing is no longer sufficient to secure modern applications. If you are selling B2B SaaS into highly regulated markets (such as finance, healthcare, or government), security must be baked into your system architecture from day one. We help your engineering teams configure automated pipelines, design secure-by-default cloud boundaries, and identify structural flaws before a single line of code is compiled.

Core SaaS Engineering Reviews

Threat Modeling & Risk Assessments: Interactive STRIDE/PASTA threat modeling sessions to map application attack vectors.
Secure SDLC & DevSecOps Design: Designing secure software deployment workflows aligned to NIST SP 800-218 (SSDF).
API Security & Architecture Audits: Verifying authentication boundaries, role-based access control (RBAC), and external data schemas.

Security that gets designed in, not bolted on after a pen test.

Reactive penetration testing catches problems after the architecture is already fixed in place. If you sell B2B SaaS into regulated markets, security decisions made early are far cheaper than the ones made after a customer security review.

TandT works with your engineering team to threat model the application, design secure-by-default cloud boundaries and find structural flaws before they ship.

Where SaaS security risk hides

Authentication and authorization boundaries that were never formally reviewed
APIs exposing more than the client actually needs
Security added after architecture decisions are already locked in
Customer security questionnaires nobody can answer with confidence

This service may be relevant if you are:

Selling SaaS into finance, healthcare or government
Responding to enterprise customer security reviews
Designing a new service or major architecture change
Building a DevSecOps pipeline for the first time

What We Do

Capabilities

01
Threat Modeling & Risk Assessments Interactive STRIDE/PASTA sessions to map application attack vectors.
02
Secure SDLC & DevSecOps Design Secure software deployment workflows aligned to NIST SP 800-218 (SSDF).
03
API Security & Architecture Audits Verifying authentication boundaries, RBAC and external data schemas.
04
Cloud Boundary Review Assessing whether cloud infrastructure is secure by default, not by exception.

How It Works

A clear path from understanding to action.

01 Discover Map the application, its data flows and its trust boundaries.
02 Threat Model Identify realistic attack paths against the actual architecture.
03 Assess Review controls, APIs and cloud configuration against the threat model.
04 Prioritize Rank findings by real business impact, not severity score alone.
05 Recommend Practical remediation your engineering team can actually implement.
