Secure SDLC — Security embedded into every stage of development, not bolted on at the end
SIRI Security designs Secure SDLC programs that embed security activities into every stage of your software development lifecycle, replacing the costly pattern of finding vulnerabilities only after release.
A security baseline the whole organisation actually follows
What does Secure SDLC involve?
Finding vulnerabilities late — in production, or worse, after an incident — is dramatically more expensive than catching them at the design or coding stage. A Secure SDLC embeds specific security activities into each phase of development rather than treating security as a final gate.
We design the specific activities appropriate to each stage — threat modeling at design, secure coding standards and SAST at development, security testing before release, and monitoring post-release — tailored to your existing development process rather than replacing it wholesale.
SIRI Security delivers Secure SDLC to this standard directly — practitioner-led, documented, and connected to SIRI Law LLP's legal and regulatory response if a finding ever needs to go further.
What organisations get wrong
Four assumptions that leave application strategy underdeveloped
Strategic AppSec gaps rarely show up in a single release — they compound quietly across many.
“We'll add security once the product is stable”
Retrofitting security into an established SDLC costs materially more than building a minimum baseline in from the start.
“Annual review is frequent enough”
A quarterly AppSec review catches drift a single annual pass consistently misses — architectures and dependencies change faster than yearly cycles account for.
“Our core app is covered, so we're fine”
Browser extensions, third-party integrations, and infrastructure components carry their own attack surface that a core-app-only review skips entirely.
“We don't need a formal security score”
An internal benchmark like a structured security score gives the board a trackable number — without one, 'more secure' has no defensible baseline to measure against.
What Secure SDLC covers
What's included, start to finish
Strategy and governance that gets built into how you ship, not reviewed after the fact.
Stage-by-stage security activities
Concrete security activities mapped to each phase of your existing SDLC.
Tooling integration guidance
SAST/DAST/SCA tooling integrated into your CI/CD pipeline where appropriate.
Secure coding standards
Standards and guidelines tailored to your languages and frameworks.
Release gate criteria
Clear, practical security criteria for release readiness.
Developer enablement
Training and support so developers can actually execute the new process.
Evidence, not guesswork
No formal AppSec strategy vs. ad hoc reviews vs. a SIRI-supported programme
The gap compounds quietly across releases until an audit or incident makes it visible all at once.

Numbers every board should know
What strategic AppSec work is actually protecting against
Of cloud detections
Trace to misconfiguration and IAM exploitation (DSCI).
Of malware detections
Are trojans and file infectors (Seqrite 2026).
Incidents CERT-In handled
In the latest reporting year — the backdrop strategic security investment is measured against.
CERT-In notification window
The deadline a defined security baseline helps make achievable.
Why SIRI for Secure SDLC specifically
Strategy set by the same team that tests it
The practitioners who define your security baseline are the same ones who test whether it actually holds.
Led directly by SIRI's Head of Cybersecurity
Vikram Rao, SIRI's Head of Cybersecurity, directs offensive security and incident response and leads CERT-In breach containment for enterprise clients.
Findings connected directly to legal exposure
SIRI Security runs under the same roof as SIRI Law LLP — when a finding carries real legal exposure, the engagement can be brought under attorney-client privilege from day one, not bolted on after the fact.
Governance built by SIRI's GRC and Compliance lead
Sneha Iyer, Associate Partner and Head of GRC and Compliance, has delivered ISO 27001, SOC 2, and SEBI CSCRF programmes across the client base this catalogue serves.
Built for RBI's specific application-security expectations
Baselines and review cadence are scoped to the standard RBI's 2026 Framework and SEBI's CSCRF expect, not a generic industry template.
Who this is built for
Organisations this strategic service is built for
How we work
From scoping to ongoing delivery
Current State Review
We review your current program, policies, and practices to establish an honest baseline.
Week 1Framework & Roadmap Design
We design the specific framework, policy, or roadmap tailored to your organisation's scale and risk profile.
Weeks 2–3Implementation Support
We support rollout and adoption, working alongside your team rather than handing over a document and leaving.
Week 4+Ongoing Governance
We help establish the ongoing governance and review cadence so the program stays current as your organisation evolves.
OngoingFrequently asked
Secure SDLC, answered directly
Does this require replacing our current development process?
No — we design the Secure SDLC to integrate with your existing process and tooling, adding security activities rather than replacing your workflow.
How does this relate to DevSecOps?
Secure SDLC defines the process and standards; our DevSecOps engagement focuses more specifically on the pipeline automation and tooling that enforces it.
How long does this engagement take?
Typically 4 to 8 weeks depending on organisational scale and how much existing documentation there is to build from.
Do you help maintain this after the initial engagement?
Yes — we offer ongoing advisory and review services to keep the program current as your organisation and its risk profile evolve.
Build the baseline, then hold it
Scope Secure SDLC.
Most engagements start with a current-state review before defining the baseline and review cadence.
