Security Built by People Who Have Broken Things

Enterprise cybersecurity by 15+ year specialists

Most security consultants have passed exams. Our team has built and broken real systems — production infrastructure, industrial control systems, cloud environments, and SaaS platforms. We bring that depth to your security programme.

What We Offer

Comprehensive solutions tailored to your specific needs and goals.

Security Architecture & Design

Build security in from the start — or retrofit it properly into what you already have. We design security architectures that protect your systems without grinding your engineering team to a halt.

  • Security architecture review and design
  • Zero trust architecture implementation
  • Network segmentation and micro-segmentation
  • Identity and access management design
3–8 weeks

Threat Modelling & Risk Assessment

Understand what you are actually defending against — before an attacker shows you. Structured threat modelling that produces actionable findings, not slide decks.

  • STRIDE and PASTA threat modelling
  • Attack surface mapping
  • Business risk quantification
  • Third-party and supply chain risk assessment
2–4 weeks

Compliance & Certification Programmes

SOC2, ISO 27001, Cyber Essentials, GDPR, NIS2 — we run the programme end-to-end, from gap assessment through audit. We have done this before and we know what auditors actually look for.

  • SOC2 Type I and Type II readiness
  • ISO 27001 implementation and certification
  • Cyber Essentials and Cyber Essentials Plus
  • GDPR and UK GDPR compliance programme
8–24 weeks

Cloud Security Hardening

AWS, Azure, or GCP environments accumulate misconfigurations fast. We assess, harden, and put guardrails in place so your cloud stays secure as it grows.

  • Cloud security posture assessment (CSPM)
  • IAM audit and least-privilege remediation
  • Network and perimeter hardening
  • Data encryption and key management
4–8 weeks

SIEM, SOC & Incident Response

Detection is only useful if someone acts on it. We design and implement detection pipelines, set up SIEM platforms, and provide incident response capability — planned or emergency.

  • SIEM platform design and implementation
  • Detection rule development
  • Log pipeline architecture
  • SOC playbook development
6–14 weeks

OT & Industrial Security

Operational technology environments have unique security constraints — you cannot just patch and reboot a production line. We apply IEC 62443 principles to secure industrial environments without disrupting operations.

  • OT/IT network segmentation design
  • IEC 62443 assessment and implementation
  • Industrial protocol security (OPC-UA, Modbus)
  • Remote access security for OT environments
4–10 weeks

Security That Works in the Real World

Protect what you have built — without slowing down the team that built it.

  • 15+ years of applied security depth across cloud, SaaS, industrial, and government environments
  • SOC2 Type II and ISO 27001 programmes delivered end-to-end — not advisory only
  • Rare IT + OT security coverage for manufacturers connecting to cloud or internet
  • UK-registered entity — meets procurement and contracting requirements for UK and EU clients
  • Senior specialists only — the people who assessed your system are the people who fix it

Our Process

A proven approach that delivers results consistently.

1

Security Assessment

1–2 weeks

We start by understanding what you have, what you are protecting, and what your real threat landscape looks like. No generic checklists — a contextual assessment specific to your business, technology, and risk appetite.

Current state security assessmentAsset and attack surface inventoryKey risk findingsThreat landscape summaryPrioritised recommendations
2

Programme Design

1 week

Based on the assessment, we design a security programme scoped to your priorities — not a maximal wish list. Fixed price, clear milestones, and a realistic timeline.

3

Implementation

4–20 weeks

We implement — architecture changes, tooling deployment, policy documentation, compliance evidence collection. We work alongside your engineering and operations teams, not around them.

4

Validation & Handover

1–2 weeks

We validate that controls work as designed, train your team, and hand over with documentation that your people can actually use. Ongoing retainer available for continuous assurance.

Why Security With DevSimplex?

We built and run production systems — Integrio.AI, InfraPilot, Learnova. We have secured them against real threats under real constraints. That operational experience makes us different from consultancies that have only ever assessed, never built.

We Build and Break — Not Just Assess

Our security team includes engineers who have built production infrastructure and specialists who have broken it during red team engagements. That combination produces findings that are both technically accurate and practically fixable.

IT and OT Security — Rare Combination

We cover both IT/cloud security and OT/industrial security. If you are connecting a factory to the cloud, we handle both sides of that boundary — not two separate firms with a gap between them.

Compliance That Actually Gets Done

We have run 40+ compliance programmes through to certification. We know what auditors look for, what evidence actually satisfies a control, and how to move fast without cutting corners.

Seniors Only — No Junior Associates

Security findings from a junior who has read the framework are not the same as findings from an engineer who has exploited the vulnerability. All assessments and implementations are led by 12–15+ year specialists.

What Our Clients Say

"We had been putting off SOC2 for two years because it felt like a black box. DevSimplex made it concrete — here is what you need, here is what it costs, here is the timeline. They delivered on all three. Three deals that were blocked are now signed."

Marcus Webb
CEO, UK FinTech SaaS

"They found IAM misconfigurations our own security team had missed for 18 months. No blame — just clear findings and a practical fix plan. The zero trust implementation has made our architecture genuinely easier to reason about."

Priya Nair
Head of Engineering, Series B SaaS Company

Frequently Asked Questions

How is this different from hiring a Big Four security consultancy?

Big Four teams are excellent at governance frameworks and board-level reporting. They are less strong on technical implementation — the actual fixing. Our team does both: we can write the ISO 27001 ISMS and harden the AWS environment that needs to comply with it. Senior engineers on every engagement, not junior associates managed by a partner.

We are a startup — do we really need formal cybersecurity?

Depends what you are building and who you are selling to. If you are selling to enterprises, you will hit a SOC2 or ISO 27001 requirement within 12–18 months — better to build it properly once than bolt it on under deadline pressure. If you handle personal data, GDPR applies from day one. We scope to your actual risk and stage — we are not here to sell you more than you need.

Can you work alongside our existing internal security team?

Yes — and we prefer it. Internal teams know the context; we bring depth in specific areas or extra capacity for a defined programme. We have embedded alongside in-house teams on SOC2 programmes, zero trust implementations, and incident responses. We do not compete with your team — we extend it.

How long does SOC2 take?

Type I (point in time) typically 10–16 weeks from gap assessment to report. Type II (audit period) requires a minimum 6-month observation window after controls are in place — so 18–28 weeks end to end, depending on your starting point. We have achieved Type II in 18 weeks for a well-prepared client. We will tell you your realistic timeline after a gap assessment.

Do you offer ongoing security retainers?

Yes. Most clients move to a retainer after the initial programme — for continuous compliance monitoring, quarterly security reviews, incident response cover, and ongoing architecture support. Retainers start at a fixed monthly fee and scale to your needs.

What happens if we have a security incident right now?

Contact us directly at hello@devsimplex.com with INCIDENT in the subject. We offer emergency incident response — containment, investigation, and recovery. Existing retainer clients get priority response within 2 hours. New clients we will respond to as fast as capacity allows. We do not turn away active incidents.

Do you cover OT and industrial security as well as IT?

Yes — and this combination is rare. Most cybersecurity firms are IT-only. Because we also do factory automation, our team understands OT environments, industrial protocols, and the operational constraints that make standard IT security approaches unworkable in manufacturing. IEC 62443 assessments and OT/IT segmentation are part of our standard offering.
