Application Security Assessment
Rigorous, OWASP-aligned security assessments for web applications, APIs, and SaaS platforms. Manual analysis that goes beyond what scanners can find — identifying business logic flaws, architecture weaknesses, and attack chains that automated tools miss.
Why Application Security Matters
Web applications and APIs are the primary attack surface for modern organizations. According to Verizon's DBIR, over 70% of breaches involve web application vulnerabilities — and most of these could have been identified before deployment with a proper security assessment.
Automated scanners catch perhaps 20–30% of real vulnerabilities. The rest — business logic flaws, authorization issues, chained attack paths — require a human attacker's perspective. That's where a manual AppSec assessment delivers value that no tool can replicate.
Whether you're a SaaS startup in Stockholm preparing for SOC 2, a fintech in Copenhagen navigating DORA compliance, or an enterprise in Berlin hardening your product before a major release — an AppSec assessment gives you the evidence-based findings you need to make confident decisions.
Every assessment I deliver prioritizes actionable findings over volume. No padding, no scanner noise — just the vulnerabilities that matter and the guidance to fix them.
What's Included
Each engagement is scoped to your specific technology stack and risk profile. Common components include:
Source Code Review
Manual review of application source code to identify insecure patterns, hardcoded secrets, injection sinks, and cryptographic weaknesses.
SAST & DAST
Static and dynamic analysis using industry-standard tooling, combined with manual validation to eliminate false positives and find what scanners miss.
Threat Modeling
STRIDE/PASTA-based threat modeling to identify high-risk attack paths in your architecture before they become exploitable vulnerabilities.
Secure SDLC Advisory
Practical recommendations for embedding security into your development process — from code review gates to dependency management and CI/CD security.
Methodology
Assessments follow a structured process aligned with OWASP ASVS, OWASP Top 10, and OWASP API Security Top 10.
Scoping
Define objectives, in-scope systems, testing approach (black/grey/white box), and success criteria.
Discovery
Enumerate application surfaces, map authentication flows, identify data trust boundaries and entry points.
Analysis
Manual testing of business logic, authorization, session management, input handling, and cryptography.
Reporting
Risk-ranked findings with CVSS scores, proof-of-concept demonstrations, and prioritized remediation guidance.
Who This Service Is For
SaaS Companies
Startups and scale-ups shipping web applications who need independent security validation before launch, investor due diligence, or SOC 2 / ISO 27001 compliance.
Fintech & Regulated Industries
Organizations under DORA, PCI DSS, or financial sector regulations that require documented security testing with risk-ranked findings.
Enterprises Shipping Products
Product teams at larger organizations who need expert AppSec review as part of secure SDLC — code review, threat modeling, and architectural risk assessment.
Frequently Asked Questions
What is an application security assessment?
A comprehensive evaluation of a software application to identify vulnerabilities, weaknesses, and misconfigurations. It combines manual code review, automated scanning (SAST/DAST), threat modeling, and business logic testing.
How does AppSec differ from a penetration test?
AppSec assessments focus on the full secure development lifecycle — architecture review, code quality, SDLC practices. Penetration tests focus on exploiting specific vulnerabilities under adversary simulation. Many engagements combine both.
What standards do you test against?
OWASP ASVS, OWASP Top 10, OWASP API Security Top 10, CWE/SANS Top 25, and NIST guidelines. For regulated sectors, assessments can align with ISO 27001, PCI DSS, or GDPR security requirements.
Do you work with companies outside Sweden?
Yes. Based in Sweden but serving clients across Scandinavia, DACH, and broader Europe. Engagements are conducted remotely or on-site depending on scope.
What deliverables do I receive?
A detailed report with executive summary, risk-ranked findings, full technical write-ups with proof-of-concept steps, CVSS scores, and actionable remediation guidance. Retest included to verify fixes.
