Security Audit — Review and Risk Assessment

Concerned about data security, facing compliance requirements, or unsure about vulnerabilities in your application and infrastructure? A security audit reveals the real state of your defenses — from server configuration and authentication mechanisms to sensitive data protection. Instead of a false sense of security, you get an objective risk assessment and a concrete action plan.

The problem

Applications deployed without a security review, servers running default configurations, dependencies with known CVE vulnerabilities, no access management policy, sensitive data stored and transmitted without adequate protection, missing security headers in HTTP responses. This is the typical picture of systems built under time pressure — functionality was the priority, security was deferred. The problem is that "later" often means "after the incident." Vulnerabilities are usually discovered only after a data breach, account takeover, or ransomware attack. The cost of a security breach — financial, reputational, and legal — far exceeds the cost of an audit. Regular security reviews allow threats to be identified and eliminated before they are exploited.

Scope of work

  • Application security review aligned with OWASP Top 10 (2021) — broken access control, cryptographic failures, injection, security misconfiguration, and the remaining categories
  • Server and infrastructure configuration review — OS hardening, firewall configuration, open ports, permissions, and service isolation
  • Access management and authentication assessment — password policies, sessions, tokens, 2FA, principle of least privilege
  • Dependency and third-party component vulnerability scan — libraries with known CVEs, outdated frameworks, unused packages
  • Security headers and SSL/TLS configuration review — Content-Security-Policy, HSTS, X-Frame-Options, protocol versions, cipher suites
  • Data handling and privacy assessment — sensitive data storage practices, encryption, logging, compliance with data minimization principles

What you get

  • Security audit report with identified vulnerabilities, attack vector descriptions, and potential consequences
  • Risk classification matrix — vulnerabilities categorized as critical, high, medium, and low with priority justification
  • Prioritized remediation plan — recommended actions ordered by risk level and implementation complexity
  • Security configuration checklist — a verification list for ongoing maintenance of correct settings
  • Executive summary with business risk assessment — key findings and risk evaluation in a non-technical format

Frequently Asked Questions

What does a security audit cover?

A security audit covers an application review aligned with OWASP Top 10 (2021), server and infrastructure configuration analysis, authentication and access management assessment, dependency vulnerability scanning, security headers and SSL/TLS configuration review, and sensitive data handling evaluation. A typical security audit takes 3-7 business days and results in a 10-30 page report depending on system complexity. The scope is tailored to the specific project — after an initial assessment, the final scope and priorities are agreed upon.

Is this the same as a penetration test?

No — these are two complementary approaches. A security audit is a systematic review of configuration, architecture, and security practices that identifies vulnerabilities through analysis and settings verification. A penetration test is an attack simulation aimed at actively exploiting discovered weaknesses. An audit provides a broader picture of the security posture, while a pentest verifies its effectiveness in practice. Audit findings can serve as the basis for commissioning a targeted penetration test.

How often should security audits be conducted?

The frequency depends on the nature of the system and regulatory requirements. For applications processing sensitive data, an audit is recommended at least once a year and after every significant architecture or infrastructure change. For e-commerce systems and financial applications — every 6–12 months. An additional review is advisable after server migration, deployment of a new framework version, or a change of hosting provider.

What happens if critical vulnerabilities are found?

Critical vulnerabilities are reported immediately — without waiting for the full audit to be completed. The report includes a vulnerability description, attack vector, potential consequences, and recommendations for immediate remediation actions. Based on the report, your team — or a chosen vendor — can implement fixes and then commission verification of their effectiveness.

Concerned about the security of your application?

A security audit reveals real threats — before they are exploited. A report with risk classification, a remediation plan, and a configuration checklist that enables you to make informed decisions about securing your system.
