Cyber threats are constant, and the cost of a breach goes far beyond money. At 5labs, we protect your business with penetration testing, security audits, vulnerability assessments, and compliance support. From GDPR and ISO 27001 to incident response and secure code reviews, our Edinburgh-based security team helps UK businesses defend their systems, data, and reputation.
Every business with an online presence is a target. Ransomware, phishing, data breaches, and application vulnerabilities are not problems reserved for large corporations. Small and medium businesses are attacked just as frequently, often with fewer defences in place. At 5labs, we provide practical, thorough cybersecurity services that match your risk profile and budget.
Our security team conducts penetration tests on web applications, APIs, mobile apps, and network infrastructure. We perform vulnerability assessments to identify weaknesses before attackers do. We review source code for security flaws, help you meet GDPR and ISO 27001 requirements, and provide incident response planning so you know exactly what to do if something goes wrong.
Cybersecurity works best when it is built into your technology from the start. Our web development team follows secure coding practices by default. Our custom software team builds applications with security baked in. For cloud infrastructure security, see our SaaS development services. Need to protect sensitive data in your applications?

Thorough protection across your applications, infrastructure, and processes
We simulate real-world attacks against your web applications, APIs, mobile apps, and network infrastructure. You receive a detailed report with every vulnerability found, its severity rating, proof of exploitation, and clear remediation steps.
Comprehensive reviews of your security posture covering infrastructure configuration, access controls, encryption practices, logging, patch management, and policy documentation. We identify gaps and prioritise fixes based on real risk.
Automated and manual scanning of your systems to identify known vulnerabilities, misconfigurations, and outdated software. We triage findings by severity and provide actionable remediation guidance, not just a list of CVEs.
We help you meet GDPR requirements for data protection, privacy policies, data processing agreements, breach notification procedures, and subject access requests. We also support ISO 27001 alignment and Cyber Essentials certification.
Line-by-line review of your application source code to find security vulnerabilities that automated tools miss. SQL injection, cross-site scripting, authentication flaws, insecure data handling, and business logic errors are all covered.
We develop incident response plans tailored to your business, so your team knows exactly what to do during a security event. We also provide post-incident analysis, forensic investigation, and recovery assistance when breaches occur.
Methodical, thorough, and focused on real-world threats
We define the scope of the engagement, identify assets to be tested, and gather intelligence about your systems. Clear rules of engagement are agreed upon before any testing begins.
Using a combination of automated scanning tools and manual testing techniques, we systematically identify vulnerabilities across your applications, APIs, servers, and network. We go beyond automated results with hands-on exploration.
We attempt to exploit discovered vulnerabilities to confirm their impact and demonstrate the real-world risk. This shows you exactly what an attacker could achieve, not just theoretical possibilities.
You receive a detailed report with every finding categorised by severity (critical, high, medium, low). Each issue includes a clear description, evidence of exploitation, business impact, and specific remediation steps.
We work with your development team to fix the identified issues. Our developers can implement fixes directly, or we provide guidance and review your patches to confirm vulnerabilities are properly resolved.
After remediation, we retest to confirm that all vulnerabilities have been properly fixed and no new issues were introduced. You receive an updated report confirming your improved security posture.
Industry-standard security tools and methodologies
Burp Suite, OWASP ZAP, Nmap, Metasploit, Nikto, SQLMap, Nessus, and custom scripts. We follow OWASP Testing Guide and PTES methodologies for comprehensive coverage.
SonarQube, Semgrep, Snyk, Dependabot, and manual review. Static and dynamic analysis of application source code across Python, JavaScript, PHP, Java, C#, and other languages.
OWASP Top 10, NIST Cybersecurity Framework, ISO 27001, GDPR, Cyber Essentials, and PCI DSS. We align our assessments with recognised standards so findings map directly to compliance requirements.

Common questions about our security testing and compliance services
Penetration testing costs depend on the scope and complexity of the target. A web application pen test typically starts from £3,000 to £8,000. Network infrastructure tests range from £5,000 to £15,000. Full-scope engagements covering multiple applications, APIs, and infrastructure are quoted based on your specific environment after a free scoping call.
We recommend a full penetration test at least once a year, and after any significant changes to your application or infrastructure. For businesses handling sensitive data or operating in regulated industries, quarterly vulnerability assessments combined with annual pen tests is the standard approach. Continuous monitoring should run alongside periodic testing.
We take every precaution to avoid disruption. Testing is planned carefully, and we agree on rules of engagement before starting. Denial-of-service testing is only performed if specifically requested and scheduled during maintenance windows. Most pen tests can be conducted against production systems without noticeable impact to users.
Yes. We conduct GDPR readiness assessments, help you document data processing activities, draft privacy policies and data processing agreements, implement technical safeguards (encryption, access controls, anonymisation), and set up breach notification procedures. We focus on practical compliance rather than paperwork for its own sake.
A vulnerability assessment identifies and catalogues known weaknesses in your systems using scanning tools and manual checks. A penetration test goes further by actively attempting to exploit those vulnerabilities to demonstrate real-world impact. Think of a vulnerability assessment as finding unlocked doors, and a pen test as actually walking through them to show what is at risk.
Yes. We can set up continuous vulnerability scanning, log monitoring, intrusion detection alerts, and security information and event management (SIEM) solutions. Ongoing monitoring catches new vulnerabilities as they emerge and detects suspicious activity in real time, complementing periodic testing.
Yes. Our secure code review service examines your codebase for vulnerabilities that automated scanners frequently miss. This includes authentication and session management flaws, injection vulnerabilities, insecure cryptographic implementations, business logic errors, and improper error handling. We review code in Python, JavaScript, TypeScript, PHP, Java, C#, and Go.
We notify you immediately. Critical findings that pose an imminent threat are reported as soon as they are confirmed, outside of the normal reporting timeline. We provide enough detail for your team to take immediate protective action, and we can assist with emergency remediation if needed. The full analysis is then included in the final report.
