# Threatplane > Threatplane helps technology businesses identify and manage security risk through expert-led threat modelling, developer training, and a self-service platform. Based in the UK, working with scale-ups and mid-market technology companies. ## Overview Threatplane gives security leaders the clarity to make risk-based decisions, and engineering teams a process that actually works — so everyone stops guessing about what to fix first. Founded in 2017, Threatplane works across the UK and Europe with clients in government, critical infrastructure, and regulated financial services. Organisations have more security data than ever — scan results, vulnerability counts, compliance scores, penetration test reports. The problem is that none of it answers the question that matters: what is the real risk to this business, and what should we fix first? The industry defaulted to tools that generate findings rather than decisions. Engineering teams work through backlogs they cannot prioritise. Security teams produce reports that do not translate into action. Boards fund programmes they cannot evaluate. Threat modelling done properly changes that starting point. You begin with what you are building, who might want to attack it, and what the consequences would be. The output is something engineering can act on, security can defend, and leadership can use to make real decisions. ### Who we work with Threatplane works with organisations where security matters and the technology is non-trivial. Client names are not published. Industries include: - Financial institutions: FCA obligations and high-value customer data that make security non-negotiable at every layer. - International airports: Passenger systems, airside operations, and infrastructure where availability failures have real-world consequences. - Government agencies: Sensitive citizen data and national security requirements. - Luxury retail: Premium brands protecting customer trust across complex global digital and physical environments. - eCommerce platforms: Peak-season resilience and payment security for platforms processing millions of transactions. - Medical research: Genomic data, patient records, and regulatory obligations. - National telecoms networks: Critical infrastructure where a security failure affects millions of people. ### How we work Fixed scope. Fixed price. Engagements have a defined start, a defined end, and a fixed price. No drawn-out discovery phases, no open-ended retainers. You know exactly what you are getting before you commit. Built for the boardroom. Every deliverable is shaped around what leadership needs — a concise, prioritised plan with clear business context, not a technical backlog. Capability transfer, not dependency. The frameworks and processes used are teachable. If your teams want to run threat modelling independently after working with Threatplane, that is actively supported. ### Common questions What is threat modeling? Threat modeling is a structured process for identifying security risks in a system before they can be exploited. You map out what you are building, who might want to attack it, and what they could do. The output is a prioritised list of risks with clear actions, not a generic checklist. Who is it for? Threat modeling works best when it involves engineering, product, and security teams together. Threatplane is designed to make that collaboration practical — you do not need a dedicated security expert to run sessions or interpret results. How long does it take? A focused threat modeling session on a single system typically takes two to four hours. A full consulting engagement runs two to four weeks. Ongoing maintenance is much lighter — usually a short review when something significant changes. Which industries do you work with? Threatplane has worked across defence and intelligence, financial services, healthcare, manufacturing, government, and e-commerce. The platform and methodology adapts to the regulatory and technical requirements of each sector. Does it integrate with existing tools? Yes. Threatplane integrates with tools engineering teams already use, including GitHub, Slack, and custom tooling via webhooks and a comprehensive API. How does pricing work? Pricing depends on the scope of the engagement or the number of applications and teams to cover. All engagements are fixed-fee. ## Services - [Threat Modelling Service](https://threatplane.com/services/threat-modelling) - [Developer Training](https://threatplane.com/services/developer-training) - [Threat Modelling Platform](https://threatplane.com/services/platform) - [Security Engineering](https://threatplane.com/services/security-engineering) - [Free Resources](https://threatplane.com/services/free-resources) ### Threat Modelling Service Most security assessments produce a list of findings. A threat model produces shared understanding — one your security team, your engineers, and your board can all work from. Most security solutions cater to generic use cases and off-the-shelf services. When applied to more complex stacks involving agentic AI, automated workflows, cloud environments, or custom-built applications, these solutions fall flat. Users receive technical security data with a severity label that has no bearing to reality. Threat modelling was designed for bespoke technology. It produces findings specific to your system, your team, and your business. Threatplane uses the RROC framework to align threat model findings to business impact across four dimensions: Revenue, Reputation, Operations, and Compliance. This reframes security findings in terms leadership can act on, and gives security leaders a clear basis for investment decisions. Each engagement follows four stages. Business context: Before touching architecture diagrams, we establish what the system does, what happens if it fails, who the realistic threat actors are, and what the risk appetite looks like. This framing drives everything that follows. Without it, threat modelling produces a generic list of concerns rather than findings the business can act on. Architecture mapping: Your engineers walk us through the real system — trust boundaries, data flows, third-party dependencies, authentication points, and the places where complexity hides. This stage routinely surfaces details the security team did not know and assumptions the engineering team had not questioned. Threat assessment: Using the STRIDE framework and the shared architecture model, we systematically identify realistic threats. Not every theoretical vulnerability — the attacks that are plausible given your threat actors, your technology, and your business context. Each threat is assessed for likelihood and impact. Controls prioritisation: The output is a prioritised set of controls mapped to business risk, with clear rationale for each recommendation. Your security team gets something they can defend. Your engineering team gets something they can build. Leadership gets a clear picture of where investment is needed and why. Standard delivery is four weeks. We can deliver in as little as two weeks. Outputs include an asset and scope inventory, a risk and business impact assessment, and a prioritised controls and remediation roadmap. ### Security Engineering After a threat model identifies gaps, Threatplane can implement the controls directly — freeing engineering teams to continue delivery without a context switch to security work. Services include control implementation (access controls, infrastructure changes, bespoke security tooling), detection engineering (precise, low-noise detections derived from the threat model so security teams are alerted when real attacks occur), and ongoing operations (monitoring, tuning, and maintenance as the system evolves). Areas of expertise include cloud-native architectures (Kubernetes, microservices, serverless), DevSecOps and CI/CD integration, AI/ML system security, and API security. ### Developer Training Training that gives engineers the skills to threat model independently — so security stays embedded in delivery, not bolted on at the end. There is no course catalogue. Training programmes are designed around the team: their current skills, how much time they have, and what the organisation is trying to achieve. All training is hands-on. Engineers learn by working through real threat modelling exercises, not slides. The methodology is the same one used in Threatplane's consulting work, which means the skills transfer directly. Training typically follows a consulting engagement. Once teams have seen the output of a threat modelling engagement, there is usually appetite to run the process themselves. The goal is internal capability, not ongoing dependency on Threatplane. All engagements are fixed-fee. ### Threat Modelling Platform Built for organisations already running threat modelling who need to do it continuously, across multiple teams and systems — without the admin burden that comes with managing it all manually. The platform has been used in Threatplane's consulting work for six years. Every feature came from a real engagement, not product assumptions. It is available to organisations that have worked with Threatplane and are ready to run their threat modelling programme independently, at greater scale. The platform handles model management across multiple systems and teams, giving a consolidated risk view for the CISO without the manual overhead of spreadsheets and documents. Reports, risk registers, and control summaries generate automatically from the model. Integration into existing developer tooling is supported via webhooks, a comprehensive API, GitHub issues, and Slack notifications. Diagramming uses draw.io, which means full-featured architecture tools are built in and existing draw.io or Lucidchart diagrams can be imported directly. Any architecture can be scoped: cloud, on-prem, hybrid, SaaS, AI systems, supply chain. Platform outputs include a threat assessment, controls assessment, risk assessment mapped to business impact, a prioritised remediation roadmap, and detective controls specific to the architecture. ### Free Resources A library of application security resources covering security best practices, vulnerability prevention guides, security checklists, and tool recommendations.
