Cybersecurity services for UK companies.
HackingByte runs senior-led, remote cybersecurity engagements for UK companies. We show how an attacker would actually reach what matters in your business — and what it would cost you — and turn the result into evidence your customers, auditors, and the ICO would recognise.
- Senior-led delivery.
- No tools sold.
- Evidence-driven reporting.
UK companies are asked to prove their security more often than ever. Procurement teams want a recent penetration test before they sign; cyber insurers ask pointed questions before they quote; and large customers send security questionnaires that expect named standards and reproducible findings, not a one-line assurance. Whether you are a SaaS vendor, a financial-services firm, a managed-service provider, or an SME signing your first enterprise contract, the bar is the same: demonstrate that your defences hold.
HackingByte S.A.R.L. works to the international standards of the trade — PTES, MITRE ATT&CK, OWASP, and the CIS Benchmarks — and names them explicitly in every scope and report. Every engagement is run by senior practitioners, delivered remotely, and ends in evidence you can act on: demonstrated attack paths, risk read in business-impact terms, and a prioritised remediation plan. Our penetration testing is the most common place UK companies start.
Senior-led, remote, evidence-first.
The technical depth your UK customers and auditors expect.
Choosing a remote provider should mean no compromise on technical depth or on how the work is run. The same senior practitioner who scopes your engagement performs the testing and writes the report — there is no hand-off to junior staff once the contract is signed. We apply the same frameworks UK and international firms cite: PTES and MITRE ATT&CK for external and internal testing, the OWASP WSTG and API Security Top 10 for web and APIs, and the CIS Benchmarks for cloud. Findings are reproducible, evidenced, and written for the audience that needs them — your engineers, your leadership, or a customer’s auditor.
Remote delivery suits how UK companies actually work: cloud-hosted estates, distributed teams, and SaaS-heavy infrastructure that is tested over the network without anyone needing to be on site. Engagements are fixed-scope and run under clear rules of engagement, with a scoping conversation up front to size the work to your real attack surface — not a templated package. We do not hold any UK scheme accreditation, and we do not claim one; what we offer is named-standard work and evidence that stands up to scrutiny. Our methodology sets out the standards we cite in every report.
Our services for UK companies.
Offensive security, assessment, and readiness — delivered remotely.
Every engagement is senior-led, fixed-scope, and evidence-first. Scope is set to your real attack surface and your actual obligations.
- Penetration testing External, internal, web, and API testing performed manually by senior practitioners — demonstrated attack paths with evidence, not a scanner export. The format a customer security review, an auditor, or a cyber insurer expects.
- Red teaming and adversary simulation Objective-based engagements for mature programmes: your detection and response tested against a realistic scenario mapped to MITRE ATT&CK, under strict rules of engagement.
- Security assessments A structured, evidence-based review of your posture — useful as triage before a full penetration test, after an incident, or when facing a buyer’s security questionnaire.
- Cloud security assessment Assessment of AWS, Azure, and GCP environments — identities, privilege paths, and the misconfigurations that chain into real impact.
- ISO 27001 readiness Gap analysis, control implementation, and audit-readiness for ISO 27001 — the certification UK enterprise buyers most often ask for.
- SOC 2 readiness Preparation for a SOC 2 examination — controls, evidence, and the technical testing behind them, for UK companies selling to North American and enterprise customers.
- UK GDPR consulting Technical and advisory support for UK GDPR — making personal-data processing demonstrable and auditable against what the ICO and your customers expect. Advisory, not legal advice.
- Cyber due diligence Security review for transactions — assessing a target’s real exposure before an acquisition, investment, or supplier onboarding decision.
The scoping conversation is free and without obligation.
The UK context.
UK GDPR, the ICO, and the NIS Regulations 2018.
The UK regime is its own. Personal-data processing is governed by the UK GDPR and the Data Protection Act 2018, regulated by the Information Commissioner’s Office (ICO), which expects appropriate technical and organisational security measures and can act when they are absent. Operators of essential services and relevant digital service providers also fall under the Network and Information Systems Regulations 2018 (the NIS Regulations), the UK’s own framework for network and information-systems security. Note that NIS 2 is an EU directive and does not apply in the UK — though UK companies with EU operations or EU customers may still inherit EU requirements through contract or jurisdiction.
Our role is to turn those requirements into evidence: a penetration test or security assessment whose findings are reproducible, a reading of risk your leadership can carry to a board, a customer, or the ICO, and a prioritised remediation plan. We do not provide legal advice — interpreting the UK GDPR or the NIS Regulations is for your counsel or your data-protection officer — but we make your security demonstrable against these frameworks. We hold no UK scheme accreditation and make no such claim; the value is in named-standard work and evidence that holds up.
Frequently asked questions
- Do you have an office in the UK?
- No. HackingByte S.A.R.L. delivers engagements for UK companies remotely. The full entity details are on the site’s Legal Notice page. Cloud, web, API, and external and internal network testing are all performed over the network without anyone needing to be on site.
- Will your reports satisfy our customers, auditors, and insurers?
- The engagement file explicitly cites the standards applied (PTES, MITRE ATT&CK, OWASP, CIS), provides reproducible evidence for every finding, and is written for the audience that needs it — the format UK customer security reviews, auditors, and cyber insurers expect.
- Are you CREST or NCSC accredited?
- No, and we do not claim to be. We work to the recognised international standards of the trade and name them in every scope and report. If your buyer or insurer specifically requires a scheme-accredited supplier, tell us at scoping so we can be clear about fit before any work begins.
- Does NIS 2 apply to my UK company?
- NIS 2 is an EU directive and does not apply in the UK; the UK framework is UK GDPR plus the ICO and the NIS Regulations 2018. That said, if your company has EU operations or EU customers, you may still face EU requirements through contract or jurisdiction. We can scope the testing and assessment work either way and work alongside your counsel, without providing legal advice.
- How do we get started?
- Start with a free, no-obligation scoping call. Tell us what is driving the need — a tender, a customer questionnaire, an insurance renewal, or a doubt after an incident — and we will set scope to your real attack surface and obligations before any work begins.
