A CREST-accredited cyber security services company
Cyphere is fully accredited by CREST for penetration testing and certified by IASME as a Cyber Essentials Plus and Cyber Assurance certification body. Cyphere is registered on the UK Government G-Cloud framework as an approved cybersecurity services provider. We at Cyphere hold professional indemnity insurance, maintain quality management standards, and operate as an independent cybersecurity services provider with no vendor ties.
We work with UK organisations of 50 to 500 staff in regulated and supply-chain-driven sectors, where security has to be evidenced rather than assumed.
We Engage With Your Security Challenges
We combine technical expertise with deep business insight to map your digital attack surface. We evaluate your people, processes, and technology controls. Our fast, accurate scoping via asset walkthroughs and architecture reviews ensures no surprises. You receive a clear view of exploitable risks ranked by business impact and compliance needs.
We Listen To Your Business Needs
We translate your requirements into proposals with flexible pricing. Our experts guide you through ISO 27001, PCI DSS, UK GDPR, and Cyber Essentials with audit-ready evidence. We don't just "report and run"; we provide practical remediation steps to help you meet certification deadlines.
We Deliver Ongoing
Protection
Service quality is the foundation of Cyphere. For managed services, our analysts scan the ongoing posture changes and incident response readiness. Every engagement includes unlimited retests, debrief calls, and 12 months of post-certification support as standard. Whether it is managed vulnerability scanning or security operations maturity, we remain your partner you can count on.
Cyber security solutions we deliver
Our cyber security solutions cover on-premise, cloud and hybrid environments. Each engagement is scoped to your estate with your drivers in mind, delivered by experienced consultants, reported with prioritised remediations you can act on and comes with 12 months unlimited retests.
Whether you are building AI features, integrating with serverless AI infrastructure or your teams are using AI tools, we assess your setup, model and prompt injection risks, data exposure through AI services, agent and API permissions, and shadow AI across your estate.
External and internal penetration tests that follow real attack paths: phishing as entry attack vector, privilege escalation, lateral movement across internal environments and data exfiltration. You get exploitable findings ranked by business risk, with remediation priorities rather than a CVE list or vendor reference link.
Tabletop exercises and live breach simulations that test your security operations, incident response procedures, communication protocols and recovery processes. Red team engagements measure how quickly your team detects and responds under pressure to a cyber attack.
AWS, Azure and Google Cloud assessments covering IAM permissions, storage exposure (S3, Azure blobs), encryption, container and serverless security, and compliance gaps against CIS benchmarks. We map remediation to infrastructure-as-code where your environment supports it.
Application and API testing covering OWASP Top 10 flaws and beyond across authentication bypass, authorisation flaws, business logic weaknesses, API abuse and mobile reverse engineering. Findings show the exact exploitation steps so developers fix root causes, not symptoms that will appear again in the next test exposing you under false assumption of fixes.
Our cyber security services and solutions
Industries We Secure
When you engage Cyphere, senior consultants lead your engagement from scoping to final debrief. You get remediation roadmaps prioritised by exploitability and business impact, exploit chains showing how an attacker would actually move through your network, and 12 months of unlimited retests as you fix what we find to practically move the needle on risk reduction. Our engagements are structured around your environment, not a standard package. Service quality is the centre of everything we do, we aren’t a ‘report and run’ company.
Our consultants work across regulated and supply-chain-driven sectors, mapping controls to ISO 27001, NIST CSF, PCI DSS, UK GDPR with audit-ready evidence and Cyber Essentials Plus Certification. Our sector specific context and awareness means practical remediations that align with your business operations and risk appetite, not the theoretical advice.

Achieve Complete Digital Protection Using Professional Risk Assessment & Monitoring
Our cybersecurity company UK delivers CREST-accredited penetration testing and continuous vulnerability monitoring across networks, applications and cloud infrastructure. We identify exploitable weaknesses, validate security controls and provide remediation guidance with specific timelines and technical fixes. Continuous threat monitoring reduces detection time from weeks to hours while ensuring compliance with ISO 27001, PCI DSS and GDPR requirements.
Identify and remediate cyber risks quickly
We prioritise findings by CVSS base score, EPSS probability and asset exposure. Critical vulnerabilities affecting internet-facing systems receive P1 status with 48-hour remediation SLAs. Medium risks on internal assets get 30-day windows. Each finding includes CVE references, exploit-db links and specific patch versions. We map vulnerabilities to MITRE ATT&CK techniques, showing exact attack chains, for example, T1190 (Exploit Public-Facing Application) → T1078 (Valid Accounts) → T1003 (OS Credential Dumping). You get working proof-of-concept code for high/critical findings and exact CLI commands for remediation. We track MTTR across categories: OS vulnerabilities average 7 days, application flaws 14 days, and configuration issues 3 days.
Stay ahead of evolving attack methods
We test using current ransomware techniques: LockBit 3.0 double extortion, Cl0p SQL injection exploits, MOVEit vulnerabilities (CVE-2023-34362), and ESXi encryption attacks. We incorporate CISA KEV catalogue checks within 24 hours of publication. Penetration tests simulate threat actors relevant to your sector: APT29 for technology firms, FIN7 for retail, Scattered Spider for telecoms. We use Cobalt Strike, Metasploit, Sliver C2 and custom Python scripts matching attacker toolkits. Testing includes living-off-the-land techniques using PowerShell, WMI, and built-in Windows tools that bypass traditional AV. We test supply chain vectors: npm package injection, Docker container escapes, Terraform misconfigurations in CI/CD pipelines.
Improve operational security posture
We validate specific controls: network segmentation with VLAN penetration attempts, MFA bypass testing through session hijacking and token replay, privilege escalation via sudo misconfigurations and SUID binaries. Configuration reviews check 300+ CIS benchmark controls across Windows Server 2019/2022, RHEL 8/9, Ubuntu 20.04/22.04. Cloud assessments test AWS IAM policies for privilege escalation paths, S3 bucket ACLs, security group rules and CloudTrail logging. We identify lateral movement paths through BloodHound analysis, Kerberoasting opportunities and NTLM relay attacks in Active Directory. Each finding includes exact registry keys, firewall rules or IAM policies to modify.
Align IT security compliance with business goals
We map controls to specific requirements: PCI DSS 4.0 sections 6.2 (vulnerability management), 11.3 (penetration testing), ISO 27001:2022 Annex A.8.8 (technical vulnerability management), GDPR Article 32 technical measures. Reports include exact clause references and evidence mapping. We quantify risk in monetary terms using factor analysis of information risk (FAIR): single loss expectancy ×annualised rate of occurrence. We provide audit-ready evidence files with timestamps, screenshots and command outputs formatted for ISO, PCI QSA and SOC 2 Type II auditors.
Continuously monitor and respond to threats
Managed scanning runs authenticated Nessus/Qualys scans weekly with daily checks for CISA KEV additions. We advise and work with customer teams to setup alert triage that follows defined escalation: P1 incidents (active exploitation) get a 15-minute response, P2 (imminent threat) 2 hours, P3 (potential risk) 8 hours. Vulnerability tracking includes Jira integration with automatic ticket assignment to asset owners. Monthly reports show patch compliance percentages, mean time to detect (MTTD), mean time to respond (MTTR), and trending across 90-day windows.
Protect brand reputation and customer trust
Cyber Essentials Plus certification is increasingly named in enterprise RFPs and asked about at insurance renewal, and insurers price against demonstrable controls. Cyber Essentials Plus certification takes 4-6 weeks, and ISO 27001 takes 6-12 months with quarterly surveillance audits. We prepare IR playbooks covering ransomware (isolate endpoints, disable backup access, notify ICO within 72 hours per GDPR Article 33), data exfiltration (block egress IPs, revoke OAuth tokens, activate DLP rules) and DDoS attacks (enable CloudFlare, contact ISP, activate anycast routing).
What makes Cyphere unique among the top Cyber Security companies in the UK?
Most providers charge for retests or bill for cancelled engagements. We include unlimited retests for 12 months for all critical and high risk issues and do not charge cancellation fees.
You get certified consultants from scoping to debrief, not junior testers learning on your infrastructure.
We understand the pricing pressures, and ensure that all pricing is transparent breakdown into level of effort against each element. Cyber Essentials Plus is £1,299 + VAT, or £999 alongside a security engagement. You do not need a discovery call to find out roughly what this costs.
Our team is more than technical heads, our formal and informal approach is central to resolving security challenges.
We are not a report-and-run consultancy.

FAQ
Why choose a CREST-accredited cyber security services company?
In the UK, CREST accreditation is the benchmark for technical competence and ethical integrity. Choosing a CREST-member firm like Cyphere ensures your penetration testing and assessments are conducted by vetted professionals to a high standard. This is often a mandatory requirement for government contracts, insurance renewals, and high-level supply chain audits.
How does Cyphere deliver an IT Health Check (ITHC)?
Our IT Health Checks are designed for private firms requiring a thorough review of their internal and external infrastructure. We provide a clear view of exploitable risks, ranked by business impact, helping you satisfy security requirements.
How do you support UK-specific compliance (ISO 27001, GDPR, NHS DSPT)?
We provide support for UK organisations navigating complex regulatory landscapes. Our team delivers audit ready evidence and gap analysis for ISO 27001, UK GDPR, and sector-specific frameworks like NHS DSPT and DTAC. We don’t just identify gaps; we guide your remediation to ensure successful certification.
What is included in a Cyber Security Assessment?
Cyber security assessment covers a holistic review of your entire security program demonstrating strengths and weaknesses of people, process and technological controls at play. It is different from a penetration test that focuses on simulation of a cyber attack against specific system, a network or an application.
Do you offer remediation support after the security audit?
We are not a “report and run” consultancy. Every engagement includes a post-test debrief and 12 months of advisory support as standard. We provide practical, actionable steps for your security teams to implement, ensuring your security transformation programme stays on track.
Do you provide Cyber Essentials and Cyber Essentials Plus certification?
Yes. We are an IASME certification body helping UK businesses achieve the Cyber Essentials Plus certification. This involves a verified technical audit of your environment – a critical requirement for any business looking to bid for UK central government contracts, demonstrate a baseline of cyber hygiene or to lower your cyber insurance premium.
Can you help develop our Security Operations (SecOps) maturity and AI strategy?
Beyond point-in-time testing, we lead security transformation projects and perform SOC maturity assessments. This includes developing SecOps maturity and creating secure AI development strategies to protect your emerging technologies against modern threat vectors.
