Enterprise security that holds the line - and proves it.
Penetration testing, SOC 2 readiness, ISO 27001 certification, and continuous threat monitoring - built for organisations where a breach isn't just expensive, it's existential.
Security that goes deeper
than a checkbox audit
From the first vulnerability scan to post-breach forensics, every engagement is led by certified security engineers who've seen the attacks firsthand - not just read about them.
Penetration Testing & VAPT
Comprehensive vulnerability assessment and penetration testing across web applications, APIs, mobile apps, and internal networks - delivered to OWASP and PTES standards.
SOC 2 Type II Readiness
We take you from zero to SOC 2 Type II report - gap assessment, policy documentation, control implementation, evidence collection, and auditor liaison. No surprises at audit time.
ISO 27001 Certification
End-to-end ISMS implementation and ISO 27001:2022 certification support. We define your scope, implement Annex A controls, manage the internal audit cycle, and prepare you for certification body review.
Cloud Security & Architecture Review
Deep-dive security review of AWS, GCP, and Azure environments - IAM posture, network segmentation, data protection controls, and misconfiguration scanning that goes beyond automated tools.
GDPR & Data Privacy Advisory
Practical GDPR compliance for technology companies - data mapping, DPIA workflows, privacy-by-design reviews, and DPA agreements. We focus on what actually reduces liability, not just paperwork.
Managed Security & Threat Monitoring
24/7 SIEM monitoring, threat intelligence feeds, and incident response - covering your endpoints, cloud workloads, and SaaS applications with human triage on every critical alert.
Compliance that opens doors,
not just ticks boxes
We've guided over 80 organisations through their first compliance programme. Here's what to expect from the four most common frameworks we deliver.
SOC 2 Type II
The de facto standard for US enterprise sales. Type II proves your controls were operating continuously over an observation period - Type I just proves they exist. Investors and enterprise procurement teams want Type II.
ISO 27001:2022
The international gold standard for information security management. ISO 27001 certification demonstrates systematic risk management across people, process, and technology - accepted in procurement processes worldwide.
GDPR
Compliance isn't optional for any organisation processing EU personal data - regardless of where you're based. We go beyond tick-the-box to build data governance that reduces actual liability and builds customer trust.
PCI-DSS v4.0
If you store, process, or transmit cardholder data, PCI-DSS isn't negotiable. Version 4.0 introduced significant customised implementation paths - we help you use them to reduce scope intelligently.
Security done by people who break things for a living
Most compliance consultants know policy. Our team also knows how attackers think - because several of us spent years on red teams before moving to helping companies defend themselves. That dual perspective is hard to replicate.
Every attack surface, covered
We test and defend against the threats your organisation actually faces - not a generic checklist.
OWASP Top 10, business logic flaws, authentication bypasses, and injection vulnerabilities across your entire web surface.
BOLA, mass assignment, excessive data exposure, and broken authentication across REST, GraphQL, and gRPC endpoints.
S3 bucket exposure, over-privileged IAM roles, publicly accessible databases, and unencrypted storage across your cloud estate.
Targeted phishing simulations, pretexting scenarios, and vishing campaigns to measure and train your team's human firewall.
Backup architecture review, lateral movement testing, privilege escalation paths, and incident response tabletop exercises.
Third-party dependency scanning, SCA tooling integration, and vendor security assessment frameworks for your critical suppliers.
Internal network segmentation testing, firewall rule analysis, wireless security, and Active Directory attack path mapping.
iOS and Android binary analysis, runtime instrumentation, local data storage review, and API communication testing.

How a Sequere security
engagement actually runs
No black-box scans, no surprise invoices. Every step is agreed upfront, with clear deliverables and access to the engineer doing the work.
A penetration test runs 2–3 weeks from kick-off to final report. A full SOC 2 programme is 4–6 months. We scope both upfront and don't move the goalposts.
Scoping & Kick-Off
A structured scoping call to define assets in scope, methodology (black/grey/white box), threat model assumptions, rules of engagement, and any compliance objectives. You'll receive a written proposal with a fixed-price quote within 48 hours.
Reconnaissance & Discovery
Passive and active reconnaissance to map your external attack surface - subdomain enumeration, technology fingerprinting, credential exposure checks on paste sites and dark web, and open-source intelligence gathering.
Active Testing
Hands-on exploitation attempts by senior engineers across all agreed-upon attack vectors. Every test is documented in real time with evidence screenshots, request/response logs, and exploitability ratings. No automated scanner dumps.
Reporting & Debrief
A detailed report covering executive summary, technical findings with CVSS scoring, root-cause analysis, and step-by-step remediation guidance. Followed by a live debrief where your engineering team can ask questions directly.
Remediation Support & Re-test
We're available to answer developer questions as remediations are implemented. A formal re-test confirms all critical and high findings are resolved before the engagement closes. Certificate of testing issued on completion.
Industry-standard tools, expert hands.
Tools are only as good as the engineers using them. We use the stack security practitioners actually rely on - not the ones with the best vendor marketing.
Three ways to work with us
Whether you need a one-off pen test before a client audit or a permanent security partner, there's an engagement model for where you are right now.
Point-in-Time Assessment
A focused security test against a defined target - a web application, API, or specific cloud environment. Ideal for pre-launch validation, supplier questionnaire responses, or satisfying a single enterprise procurement requirement.
- Defined scope, fixed deliverable
- OWASP/PTES methodology
- Executive + technical report
- Re-test included
Compliance Programme
End-to-end delivery of SOC 2 Type II, ISO 27001, or PCI-DSS - from gap analysis to audit-ready documentation. Includes all policy templates, evidence collection workflows, and auditor liaison. The most common engagement for Series A+ companies.
- Gap assessment & roadmap
- Full control implementation
- Policy & procedure library
- Auditor liaison & prep
Retained Security Partner
A dedicated security function embedded in your organisation - quarterly pen tests, annual compliance renewals, continuous monitoring, security awareness training, and a named CISO-as-a-Service contact for board-level queries.
- Quarterly penetration tests
- Annual compliance maintenance
- 24/7 threat monitoring
- Virtual CISO (vCISO) access
