Application Security Consulting

Security built
into the way
you build.

Most security problems aren't discovered during audits. They're written into codebases, baked into APIs, and shipped to production. KSG works with engineering teams to fix that — before it becomes a breach.

Your engineers are moving fast. Security isn't keeping up.

Most startups and growing software teams know security matters. They also know they can't afford a full-time security hire — and that bolt-on security reviews after the fact rarely catch what's already embedded in the architecture.

KSG embeds security thinking directly into your engineering process, at the pace your team actually works.

What We Do

Three ways we work
with engineering teams.

01 / 03

Secure Code Review

A structured review of your codebase for security vulnerabilities, anti-patterns, and compliance gaps — with actionable remediation guidance your engineers can actually use.

  • OWASP Top 10 coverage
  • Authentication & authorization flows
  • Secrets handling & credential exposure
  • Input validation & injection risks
  • Written report with prioritized findings
02 / 03

API Security Assessment

APIs are your largest attack surface. We assess your endpoints, authentication mechanisms, data exposure, and access control models against real-world threat patterns.

  • Endpoint exposure & access control audit
  • Authentication & token security review
  • Rate limiting & abuse vector analysis
  • Sensitive data exposure in responses
  • Findings mapped to OWASP API Top 10
03 / 03

AppSec Training for Dev Teams

Security tools don't change behaviour. Education does. We run practical, codebase-relevant training sessions that give your engineers the mental models to write secure code by default.

  • Tailored to your stack & threat model
  • Secure coding patterns & anti-patterns
  • Live code walkthroughs
  • Secrets management best practices
  • Ongoing reference materials included

Kariba Security Group was founded on a simple observation: most application security problems aren't mysterious. They're patterns. The same authentication misconfigurations, the same secrets in environment variables, the same over-permissive service accounts — showing up in codebase after codebase, in company after company.

The reason they persist isn't that engineers don't care. It's that security expertise isn't evenly distributed — and most growing teams don't have someone whose full-time job is thinking about how their systems get broken.

KSG's founder has spent 13 years building the kind of systems you're building — high-volume APIs, payment flows, microservices architectures, distributed systems under acquisition pressure. The work we do is informed by having written the code, not just reviewed it.

We work with engineering leaders and CTOs at software companies and startups who know security is a gap — and want a practical partner to close it, not a compliance checkbox.

How It Works

From first conversation
to secured codebase.

01

Discovery Call

30 minutes. We learn about your stack, your team, and where you feel most exposed. No sales pitch — just an honest conversation about fit.

02

Scoped Proposal

We send a clear, fixed-scope proposal with deliverables, timeline, and pricing. No ambiguity about what you're getting.

03

Engagement

We do the work. You get regular updates. We flag critical findings immediately — we don't wait for the final report to tell you something important.

04

Actionable Handoff

A clear written report with prioritized findings, remediation guidance, and a debrief session so your team understands the why, not just the what.
