CONFIDENCE THROUGH SECURITY TESTING.

Security weaknesses are often only discovered after an incident. Krypsys helps organisations identify and address those weaknesses before attackers do.

WHAT WE DO

01

Penetration Testing

Manual, adversarial testing of your infrastructure to identify and exploit vulnerabilities before attackers do.

Our CREST-certified consultants simulate real-world attacks across your network, applications, and physical perimeter using the same tools and techniques employed by sophisticated threat actors. Every engagement is scoped to your environment and risk appetite — from black-box external testing to full red team operations with assumed breach scenarios. Findings are documented with proof-of-concept evidence, prioritised by business impact, and delivered with a structured debrief for your technical team.

02

Remote Access Security Assessment

In-depth evaluation of VPNs, remote desktop, and third-party access points for misconfigurations and weaknesses.

We evaluate every pathway through which remote users connect to your environment, including VPN gateways, RDP endpoints, Citrix, and third-party vendor access. Common findings include weak multi-factor authentication, split-tunnelling misconfigurations, and overprivileged accounts with persistent access that bypass perimeter controls entirely. Recommendations are mapped to your specific remote access architecture with clear, prioritised remediation steps.

03

Security Compliance

Gap analysis and technical testing aligned to regulatory frameworks including PCI-DSS, ISO 27001, and Cyber Essentials.

We map your current security posture against your target framework and identify the specific technical and procedural gaps standing between you and certification. Our consultants have direct experience supporting PCI-DSS QSA assessments, ISO 27001 Stage 1 and Stage 2 audits, and Cyber Essentials Plus technical verification. You receive a prioritised remediation roadmap with realistic timelines and evidence requirements clearly defined.

04

Web Application Security Assessment

Manual OWASP-aligned testing of authentication, authorisation, injection flaws, and business logic vulnerabilities.

Testing follows the OWASP Testing Guide and covers the full attack surface — authentication bypass, broken access controls, injection vulnerabilities, insecure direct object references, SSRF, XXE, and business logic abuse unique to your application. We test both authenticated and unauthenticated contexts, including REST and GraphQL APIs, WebSockets, and third-party integrations. All findings include detailed reproduction steps, CVSS scores, and developer-friendly remediation guidance.

05

Mobile App Security Assessment

Static and dynamic analysis of iOS and Android applications targeting insecure data storage, APIs, and authentication.

We assess iOS and Android applications against the OWASP Mobile Application Security Verification Standard (MASVS), combining static binary analysis with dynamic runtime testing on both jailbroken and stock devices. Common findings include hardcoded API keys, insecure local data storage, weak session management, and exploitable certificate pinning implementations. Testing scope covers both the mobile client and the backend API infrastructure it communicates with.

06

Vulnerability Assessment

Systematic scanning and manual validation of vulnerabilities across your estate, prioritised by real-world exploitability.

Our assessments combine authenticated and unauthenticated scanning with manual validation to eliminate false positives and surface vulnerabilities that automated tools miss. Each finding is assessed for exploitability in your specific environment rather than assigned a theoretical severity score in isolation. You receive a clear report with a prioritised remediation queue, patch guidance, and compensating control recommendations where immediate patching is not feasible.

07

Wireless Testing

Assessment of Wi-Fi networks, rogue access point detection, and wireless authentication weaknesses.

We assess your Wi-Fi infrastructure from the perspective of an attacker within radio range, testing for weak encryption protocols, rogue and evil twin access points, and PMKID-based authentication attacks. Corporate WLANs, guest networks, and IoT segments are all in scope, with signal leakage surveying to identify coverage extending beyond your physical perimeter. Findings include targeted hardening recommendations for each identified network segment.

08

ISO 27001 Consulting

Practical guidance and technical support to achieve and maintain ISO 27001 certification across your organisation.

We guide you through the full ISO 27001 lifecycle — from initial gap analysis and risk assessment through Statement of Applicability development, control implementation, and certification audit preparation. Our consultants have delivered ISO 27001 programmes across financial services, healthcare, and technology sectors, and know what certification bodies actually look for. We focus on building an ISMS that is practical and proportionate to your organisation, not just one that satisfies an auditor.
