Specialised AppSec services for vendors

AppSec expertise you can’t hire fast enough.

Securisource accelerates AppSec roadmaps. Our static analysis and AI specialists deliver security rules, languages, and frameworks, close benchmark gaps, and build the AI features your customers now expect. Since 2019 we’ve worked with dozens of vendors, including more than half of the Leaders in Gartner’s Magic Quadrant.

Why vendors call us

Four problems we’ve solved for dozens of vendors.

01

You need talent you cannot hire.

People who understand both compilers and vulnerabilities are rare. Hiring them takes months. Training engineers in security, or researchers in engineering, takes years. Ours start on day one.

02

Your customers expect AI.

Buyers now expect AI-assisted triage, fixes, and analysis. We build AI features that hold up on real code, because we have built them for ourselves.

03

You are losing benchmarks and bake-offs.

We know how evaluations are run and where products fall short in them. We find the gaps that are costing you deals and close them.

04

Your roadmap is outrunning your team.

New languages, new frameworks, new integrations. We add capacity that already knows the domain, so your core team stays on what only they can do.

AI & AppSec

AppSec is moving to AI. We’re already there.

Large language models are changing how AppSec tools find, triage, and fix issues. Our in-house AI team has built working systems at that intersection, on top of twenty years of static analysis.

Codebase-aware rule generation

A custom scanner that writes bespoke security rules for each codebase.

Custom triage

Triage systems that rank, deduplicate, and explain findings, with checks that catch the cases where a model gets it wrong.

AppSec data platforms

Platforms that bring findings from many tools together, so teams can report on, prioritise, and act on them in one place.

Context and memory for AI agents

Our own platform that gives AI coding agents durable knowledge of a codebase.

A model that finds more issues is only useful if you can measure how many of them are real. We start every AI engagement with the evaluation, not the prompt.
Results

Experience is what makes it fast.

Partnerships measured in years, interventions measured in weeks. All of them worked because we knew the right approach before we started.

Long-term R&D partnership
20x+

20+ languages. Hundreds of rules. Multi-million-dollar deals.

A long-standing engagement as an extension of a vendor’s R&D team, implementing security rules across more than 20 languages. That coverage helped the vendor win multi-million-dollar deals.

Two-month intervention
30% → ~100%

From 30% coverage to near-full in two months.

A vendor’s benchmark results showed fundamental gaps. In two months we lifted coverage of statically detectable issues from 30% to near-full, on par with their competitors.

5+ year R&D partnership

A self-managed team alongside one vendor’s core R&D.

For more than five years we have run a fully self-managed project team that works with a vendor’s R&D and product teams, with minimal attrition.

What we do

From the analysis engine to the market.

01

Language and framework acceleration

New languages, frameworks, and security rules, delivered end-to-end by a self-managed team.

02

Analysis engine engineering

Core program analysis, parser and compiler front ends, and custom rules engines, from people who have built them.

03

Benchmarking

Find out where your product stands, then keep it there as it changes.

04

Competitor analysis

How your product compares with the major SAST tools, and what it takes to close the gaps.

05

L2 support augmentation

We burn down your L2 support backlog and keep it down, so your core team stays on the roadmap.

06

AI for AppSec products

Generative AI and agentic features for AppSec products, from a team with research and hands-on experience in both.

07

Developer tooling and platforms

IDE plugins, reporting, and complete SaaS platforms for AppSec products.

08

Industry, product, and market consulting

Standards expertise, customer voice, and market guidance from people who know this market from the inside.

Our story

We’ve built the engines. Now we help vendors build theirs.

Most consultancies learn AppSec from the outside. We started by writing a static analysis engine, and we have worked inside the industry ever since.

  1. 2004–2010

    Deep-tech SAST R&D

    Research at UNSW and CSIRO (NICTA) into core analysis engines, formal methods, AI, compilers, and programming languages.

  2. 2010–2019

    Product development

    We built a commercial static analysis engine, acquired by Black Duck (Synopsys) and integrated into Coverity, then the market leader for C and C++.

  3. 2019+

    AppSec services

    Securisource founded. Since then: 300+ security rules, 20+ languages, 100+ frameworks, and benchmarking.

  4. Today

    AppSec and AI

    Generative AI and agentic systems for AppSec, built on everything that came before.

How we work

Expertise on day one, not month six.

End‑to‑end delivery.

Self-contained delivery, including project management. We run the team and report against agreed delivery KPIs.

The right expert for each task.

We assign specialists from our pool to each task by fit, and change the mix as the work changes.

Close communication.

We work inside your process and tools, with monthly check-ins. Our longest partnership has run 5+ years with minimal attrition.

Both sides of the problem.

Engineers who think like security researchers. Researchers who ship like engineers.

No ramp-up.

We have done this work countless times, for many vendors. We know what to do and how to do it.

How we engage

For security teams

Buying AppSec tools? Get an insider’s view.

We help security teams choose, roll out, and tune AppSec tools, with first-hand knowledge of how each product behaves on real code.

FAQ

Common questions.

Do you work with our competitors?

We keep a strict firewall between every client. You won’t know who else we work with, and they won’t know about you. Your roadmap, your gaps, and your results stay yours.

Who will work on our project?

Specialists from our pool, assigned to each task by fit. We manage the team and the delivery, including project management.

How do engagements work?

Short or long term, with a defined scope. We manage the project team and delivery KPIs, and work inside your process with monthly check-ins.

Where are you based?

Our team is in Sydney. We work remotely with clients in the US, the UK, Europe, Singapore, Israel, Switzerland, and elsewhere.

Do you do penetration testing?

No. We work with the vendors who build AppSec products, and with the security teams who adopt them.
