APPLICATION & PRODUCT / SECURITY

Build Security Into
Every Stage of the Product.

Modern products are built across code, APIs, cloud infrastructure, third-party dependencies and rapidly changing development pipelines. TMG Security helps organizations integrate security into the product lifecycle — from architecture and design through development, testing and deployment.

Not every stage includes every activity on every engagement. The point is that security decisions exist throughout the lifecycle, not only at the end of it.

A finding at design costs a conversation. The same finding after launch costs a migration, a release window and somebody’s weekend. Nothing about the issue changed — only how much of the system had been built on top of it.

// THE MODERN APPLICATION ATTACK SURFACE

Your Application Is More Than Its Code.

Eight layers, each with its own failure modes. Most findings live between two of them, not inside one.

// THE SECURE PRODUCT LIFECYCLE

Security Should Move With the Product.

Scroll to travel along the delivery pipeline, one stage at a time.

TRAVELLING THE DELIVERY PIPELINE

01 / 06

PLAN

Security requirements agreed before work starts.

CHECKPOINT — REQUIREMENTS

02 / 06

DESIGN

Threat modelling while the architecture can still change.

CHECKPOINT — THREAT MODEL

03 / 06

CODE

Secure coding practices and security-focused review.

CHECKPOINT — CODE REVIEW

04 / 06

BUILD

Automated checks: dependencies, secrets, static analysis.

CHECKPOINT — SAST + DEPENDENCIES

05 / 06

TEST

Application security testing against a running build.

CHECKPOINT — DAST + TESTING

06 / 06

DEPLOY

Validation that what shipped matches what was approved.

CHECKPOINT — SECURITY VALIDATION

// LIFECYCLE STAGES

Seven stages, each with something security can contribute.

// CODE TO RUNTIME

Security Has to Follow the Application.

The same application looks different at each step, and needs a different kind of check.

SECURITY THROUGH THE LIFECYCLE — ILLUSTRATIVE

// security requirement, agreed at planning

REQ-114 Every endpoint returning customer records

must authorize on the object, not only the session.

// design — recorded during threat modelling

BOUNDARY api-gateway -> orders-service

trust: partial auth: service token data: PII

// build — checks that run without being remembered

PASS dependency inventory generated

WARN transitive dependency two majors behind

PASS no credentials detected in source

// test — findings routed to the team that owns the code

OPEN object-level authorization gap -> orders-service

owner: payments squad validated: yes retest: pending

CONCEPTUAL EXAMPLE — NOT REAL PROJECT DATA

// SHIFT LEFT, WITHOUT LOSING THE BIG PICTURE

Find Problems Early. Validate Them Where They Matter.

LATE DISCOVERY

CODE

DEPLOY

PROBLEM FOUND

The problem existed from the first design decision. It was found once everything had been built on top of it.

SECURITY THROUGHOUT DEVELOPMENT

DESIGNCHECK

CODECHECK

BUILDCHECK

TESTCHECK

DEPLOYCHECK

Smaller checks, earlier, where changing the answer is still cheap — and a final validation where it counts.

Early security feedback can reduce the cost of remediation and give development teams better visibility into the security of what they are building. We would rather describe that mechanism than attach a percentage to it — the number would depend entirely on your codebase, your release cadence and your team.

Shifting left is also not the same as shifting everything. Some findings only appear in a running system with real configuration, which is why validation still belongs later in the lifecycle.

// WHAT WE LOOK AT

Twelve categories, assessed in context.

Categories we examine, described at a level useful for scoping. Findings are documented with technical detail privately to your team.

// FROM FINDING TO FIXING

Security Findings Should Improve the Product.

DISCOVERIdentify the weakness.
VALIDATEConfirm it is real and reachable.
PRIORITIZERank it against this product.
REMEDIATEGuidance the team can act on.
RETESTVerify the fix holds.
IMPROVEFeed it back into how the product is built.

A useful security process does not end with a vulnerability report. The goal is to give development and security teams enough context to answer five questions without needing us in the room.

What is wrong

The weakness, described precisely.

Why it matters

What it means for this product.

Where it exists

The component, endpoint or design decision.

How to address it

A change the team can actually make.

How to validate

What proves the fix worked.

// WHEN THIS APPLIES

When Should Security Enter the Product Lifecycle?

01SITUATIONNEW PRODUCTBefore launch, understand architecture and security requirements.

02SITUATIONMAJOR RELEASEValidate changes before they reach production.

03SITUATIONNEW APIAssess new application interfaces and data flows.

04SITUATIONNEW CLOUD ARCHITECTUREReview how infrastructure changes affect application security.

05SITUATIONRAPID DEVELOPMENTIntegrate security into fast-moving development workflows.

06SITUATIONACQUISITION / PLATFORM CHANGEUnderstand security implications of a new technology stack.

// WHAT YOU RECEIVE

Output your team can act on.

Which of these apply depends on engagement scope.

SECURITY FINDINGS

Weaknesses identified across the application in scope, with the reasoning behind each.

TECHNICAL EVIDENCE

Reproduction detail so an engineer can confirm a finding rather than take it on trust.

RISK CONTEXT

What a finding means for this product, not a generic severity label.

ARCHITECTURE OBSERVATIONS

Design-level issues that no single code change will resolve.

REMEDIATION GUIDANCE

Practical direction, including where in the codebase or design the fix belongs.

PRIORITIZED RECOMMENDATIONS

An order of work that fits how your team actually plans.

RETEST / VALIDATION

Verification that addressed findings no longer reproduce, within the agreed retest scope.

// WHY TMG SECURITY

How this practice is put together.

01 — SECURITY + DEVELOPMENT

Understand security in the context of modern software development.

02 — ATTACK-SURFACE THINKING

Look beyond individual vulnerabilities.

03 — APPLICATION + API CONTEXT

Connect application behavior with the systems supporting it.

04 — ARCHITECTURE-AWARE

Consider design decisions and trust boundaries.

05 — PRACTICAL SECURITY

Focus on findings that teams can understand and act on.

06 — SECURITY ECOSYSTEM

Connect application security with offensive, cloud and defensive capabilities.

// ONE ECOSYSTEM

The product, the environment, and the proof.

Each practice answers a different question about the same system.

APPLICATION & PRODUCT Understand the product Design, code, dependencies and pipeline — how the thing is built and where that creates risk. YOU ARE HERE CLOUD & INFRASTRUCTURE Understand the environment Identity, configuration and exposure across the infrastructure the product runs on.

SECURE DIGITAL PRODUCT Design informs the environment. The environment informs testing. Testing informs the next design decision.

Build Security Into the Product — Before It Becomes the Problem.

Whether you are building a new application, modernizing an existing product, introducing APIs, adopting DevSecOps or reviewing application architecture, TMG Security can help you identify security considerations throughout the product lifecycle.
