What I Deliver
Application Security Services
Every engagement is scoped to the organisation's stack, team maturity, and security objectives. No off-the-shelf methodology — operational experience applied to your actual codebase and architecture.
01 / SAST
Static Application Security Testing
Analysis of source code, bytecode, or binaries without executing the program. Identifies injection flaws, insecure configurations, hard-coded secrets, and logic errors during development — where fixes cost the least and have the highest impact on security posture.
02 / DAST
Dynamic Application Security Testing
Black-box testing of a running application, simulating real attacker behaviour at runtime. Catches authentication bypasses, session flaws, injection chains, and configuration vulnerabilities that static analysis cannot see — because they only appear when the application is executing.
03 / SECURE CODE REVIEW
Manual Secure Code Review
Expert-led review of the application codebase — going beyond automated tooling to identify business logic flaws, cryptographic weaknesses, chained vulnerability paths, and developer blind spots that scanners consistently miss because they require understanding application intent, not just pattern matching.
04 / THREAT MODELLING
Threat Modelling
Structured identification of threats, attack vectors, and mitigations for the application architecture — conducted as a working session with development and security teams. Output is an actionable risk register with prioritised controls, not a theoretical diagram that never gets implemented.
05 / SECURE SDLC
Secure SDLC Design
Embedding security controls into the development lifecycle — from requirements to deployment. Covers security requirements definition, threat modelling at design stage, toolchain selection, security gates in CI/CD pipelines, and AppSec maturity roadmapping aligned to OWASP SAMM.
06 / APPSEC PROGRAMME
AppSec Programme Design & Advisory
End-to-end design of an organisation's application security programme — covering governance, toolchain architecture, security champion programme design, developer security training strategy, vulnerability management process, and AppSec KPIs and metrics framework.
Who I Work With
Built for Enterprise Security & Development Teams
AppSec consulting engagements are structured around your industry, regulatory environment, and development team's current security maturity — not a generic service catalogue.
Banking & Fintech
Financial Institutions
Regulatory-aware AppSec for banks, NBFCs, and fintech platforms. Experience with central banking institutions and commercial banks across Asia and Africa.
Enterprise Technology
Product & Platform Teams
Security assessment and secure code review for product engineering teams building at scale. Past engagements include Samsung R&D and Siemens Healthineers.
Government & Defence
Public Sector Organisations
AppSec consulting for government agencies and defence organisations requiring high-assurance application security assessments and targeted security architecture review.
Healthcare
Health Tech & Medical Devices
Application security for healthcare software and medical device platforms where data integrity, patient privacy, and rigorous secure SDLC practices are non-negotiable.
Where AppSec Fits
Security at Every Stage of Development.
The cost of fixing a vulnerability multiplies at every stage it is missed. Catching it in requirements costs nothing. Catching it after a breach costs everything. AppSec consulting embeds the right controls at each stage of your SDLC.
Principle
A vulnerability found in requirements costs ~$100 to fix. The same vulnerability found in production costs ~$10,000. Shift-left AppSec is not a philosophy — it is a measurable cost reduction strategy. SAST, threat modelling, and secure code review are the tools that make it operational. For organisations integrating security into their delivery pipeline, this connects directly to the DevSecOps advisory service →
Engagement Process
How Every Engagement Runs
Scope is agreed in writing before any work begins. Findings are graded by real exploitability — not automated scanner severity scores alone. Every engagement ends with remediation support, not just a report.
Discovery & Scoping
30-minute call to understand the technology stack, team structure, regulatory context, and security objectives. Scope, timeline, and deliverables are confirmed in writing before any work begins.
Assessment
Active security testing using OWASP, PTES, and NIST methodology. Automated scanning combined with deep manual expert analysis — because automated tools miss the vulnerabilities that matter most.
Technical Findings Report
Every finding classified by severity (Critical/High/Medium/Low), CVSS v3.1 scored, evidence documented, and specific remediation steps written for the development team to act on immediately.
Remediation Support
Walkthrough with security and development teams — clarifying findings, explaining root causes, and validating that fixes address the underlying vulnerability, not just the surface symptom.
Retest & Verification Report
Verification testing of remediated vulnerabilities with a written retest report confirming resolution status — suitable for internal sign-off, audit evidence, and board-level remediation tracking.
What You Receive
Engagement Deliverables
Every engagement produces documentation that serves both technical teams and security leadership — not a single generic report sent to everyone.
Executive Summary
Risk-focused summary for security leadership and management. Covers overall application security posture, critical findings in plain language, business impact, and a prioritised remediation roadmap.
Technical Findings Report
Detailed report for development and security teams. Every finding includes CVSS v3.1 score, CWE classification, proof-of-concept evidence, affected components, and step-by-step remediation guidance.
Proof-of-Concept Evidence
Screenshots, request/response captures, payloads, and reproduction steps for every confirmed vulnerability — so developers can reproduce and verify the finding before and after remediation.
Attack Path Mapping
Visual documentation of chained vulnerabilities — showing how individual issues can be combined to achieve critical impact. Gives leadership a real picture of exploitability, not just a count of issues.
Remediation Debrief
Live walkthrough session with security and development teams. Findings explained, root causes clarified, and remediation approaches validated before your team begins fixing.
Retest & Verification Report
Written retest report confirming which findings have been resolved, which remain open, and current residual risk posture — suitable for audit evidence and internal security sign-off.
Methodology & Frameworks
Standards-Aligned Assessment
Assessments are grounded in globally recognised frameworks — giving organisations confidence that findings are comparable to industry benchmarks and defensible in audit and compliance contexts.
Web & API
OWASP Testing Guide v4.2
Primary methodology for web application security assessments. Covers all major vulnerability categories with reproducible test procedures.
API Security
OWASP API Security Top 10
Dedicated API security methodology covering BOLA, authentication weaknesses, mass assignment, improper asset management, and injection via API endpoints.
Mobile
OWASP MSTG
Mobile Security Testing Guide for Android and iOS — covering static analysis, dynamic testing, network traffic, and platform-specific attack surfaces.
AppSec Maturity
OWASP SAMM
Software Assurance Maturity Model — used for AppSec programme design, maturity assessment, and roadmapping. Maps security practices across Governance, Design, Implementation, Verification, and Operations.
Vulnerability Scoring
CVSS v3.1 & CWE
All findings scored using CVSS v3.1 and classified using CWE identifiers — enabling consistent severity comparison and integration with vulnerability management platforms.
Secure Coding
CASE .NET & OWASP Top 10
Secure code review and developer advisory grounded in the CASE .NET framework and OWASP Top 10 — covering language-specific secure coding patterns and common vulnerability root causes.
Engagement Models
How We Work Together
AppSec consulting does not fit a single delivery model. The right format depends on scope, urgency, and whether the organisation needs a one-time assessment or ongoing security programme support.
Point-in-Time Assessment
Defined-scope security assessment — web application, API, codebase review, or threat model. Fixed timeline, fixed deliverable. Suited to pre-release security validation, compliance requirements, or periodic assessment cycles.
Ongoing Advisory Retainer
Monthly advisory — fixed hours per month for security review of in-progress development, architecture consultation, and security decision support. Suited to teams that need AppSec expertise without a full-time hire.
AppSec Programme Build
End-to-end design and implementation of an application security programme — governance, toolchain, SDLC integration, developer training strategy, and metrics framework. For organisations establishing their first formal AppSec practice.
Independent Programme Review
Independent expert review of an existing AppSec programme or security assessment. Produces an objective gap analysis with recommendations — useful before major investment decisions or regulatory audits.
Common Questions
Frequently Asked Questions
What is application security consulting?
+Application security consulting involves assessing, testing, and improving the security of software applications through SAST, DAST, secure code review, threat modelling, and secure SDLC design. An AppSec consultant works directly with development and security teams to identify and eliminate vulnerabilities before they reach production — where fixing them costs 30x more than catching them during development.
What is the difference between SAST and DAST?
+SAST (Static Application Security Testing) analyses source code without executing it — finding vulnerabilities during development before deployment. DAST (Dynamic Application Security Testing) tests a running application from the outside, simulating real attacker behaviour to find issues that only appear at runtime. A mature AppSec programme uses both: SAST early in the SDLC catches issues cheaply, DAST before and after deployment catches runtime and configuration vulnerabilities that static analysis cannot see.
What does a manual secure code review find that SAST tools miss?
+Automated SAST tools miss business logic flaws, complex authentication weaknesses, chained vulnerability paths, and context-specific issues that require understanding how the application is supposed to behave. Manual secure code review examines the code with business context — finding the vulnerabilities that matter most, not just the ones that match a rule signature. High-severity findings from manual review are routinely those that would survive an automated-only assessment entirely undetected.
Can the engagement be customised for our technology stack?
+Yes. Every engagement is scoped to the organisation's specific stack, framework, and development environment. Whether the team works in .NET, Java, Python, Node.js, or a microservices architecture, the assessment methodology and remediation guidance are tailored accordingly. The 30-minute discovery call is specifically for this scoping conversation before any work begins.
What certifications are relevant to your AppSec consulting work?
+The primary AppSec-specific credential is CASE .NET (Certified Application Security Engineer for .NET) from EC-Council, validating expertise in application security engineering, threat modelling, and secure coding for the .NET ecosystem. Additional active credentials: CEH Master, CPENT, LPT Master, CHFI — all from EC-Council.
How long does a typical AppSec engagement take?
+Duration depends on scope. A focused web application security assessment for a single application typically runs 5–10 working days including reporting. A full AppSec programme design (threat modelling + SDLC design) is typically 3–4 weeks. Retainer arrangements for ongoing advisory are also available. All timelines are confirmed during scoping before any work begins.
Are onsite AppSec engagements available internationally?
+Yes. Both onsite and remote formats are available globally. Onsite engagements have been conducted across Asia, the Middle East, Africa, and Southeast Asia. Travel logistics and onsite delivery requirements are confirmed during the scoping call.
