Most UK businesses reach a point where managing security incidents by email thread and shared spreadsheet stops working. Someone misses a notification. An escalation falls through the cracks. An auditor asks for evidence of timely detection and response, and nobody can produce it cleanly. That is usually when teams start looking at incident management software.
The problem is that most off-the-shelf options are built for Silicon Valley engineering teams or massive enterprises with six-figure implementation budgets. UK mid-market businesses get stuck in the middle: too complex for simple ticketing tools, too cost-conscious for enterprise platforms, and too specific in their compliance and workflow requirements for generic SaaS.
We build custom security incident management software for UK businesses that need their tools to match how they actually work, not the other way round.
Where off-the-shelf incident management software falls short
The SaaS incident management market is crowded, but the complaints we hear tend to cluster around the same problems:
Per-user pricing that punishes growth. Tools like PagerDuty charge £21-41 per user per month. That is manageable with 10 on-call engineers, but at 50+ staff you are looking at £45,000-75,000 over three years, and the number goes up every time you hire. Add-ons like AIOps (£699/month extra) and advanced analytics push costs further. There is no per-incident or per-alert pricing available, so quiet months cost the same as busy ones.
Escalation logic that doesn’t match your business. Off-the-shelf escalation policies are rigid. You get basic chains like “team lead, then manager, then director.” But real-world escalation often depends on context: which customer is affected, what revenue is at risk, whether it is a security incident or an operational one, what time zone your responders are in. SaaS tools require complex rule stacking to approximate this, and it breaks easily.
Vendor instability. Atlassian is shutting down Opsgenie in April 2027 and forcing customers onto Jira Service Management. If you have built workflows, on-call schedules, and integrations around Opsgenie, you are now facing a mandatory migration on someone else’s timetable. This is not hypothetical; it is happening right now to real teams.
Slack dependency. Several modern platforms, Incident.io being the most prominent, are built entirely around Slack. If your organisation uses Microsoft Teams, or if you need incident workflows that extend beyond chat into legacy enterprise systems, these tools create friction rather than removing it.
Compliance gaps. Most SaaS platforms default to US-hosted data centres. That creates GDPR risk for incident records containing personal data. Audit trail features often exist but are not formatted the way UK auditors expect for ISO 27001 or NIS2. And immutable logging, where records cannot be edited or deleted after creation, is rarely built in at the architecture level.
Integration pain with legacy tools. If you are running on-premise monitoring (Nagios, Splunk), a custom CMDB, or bespoke ticketing systems, SaaS incident platforms offer limited integration. You end up manually copying alert data between tools, which defeats the purpose of having a centralised system.
Alert fatigue. Commercial SIEMs can generate thousands of alerts daily. Without domain-specific deduplication and severity calculation, your incident management platform becomes just another noisy channel that people learn to ignore.
What we build instead
We build incident management systems that reflect how your organisation actually handles security events, from first alert through to postmortem and remediation tracking.
Your escalation logic, not theirs. We implement context-aware routing: escalate differently based on customer tier, revenue impact, incident type, or time of day. Your on-call schedules account for time zones, holidays, and workload fairness across your team. The system follows your existing protocols rather than forcing you to redesign them.
You own the system. No per-user licensing. No annual price increases. No vendor deciding to discontinue your platform. You get the source code, you choose where it is hosted, and your support costs stay predictable regardless of how many people use it.
Built for your compliance requirements. GDPR breach notification tracking, ISO 27001 immutable audit trails, NIS2 reporting timelines, FCA incident logging, Cyber Essentials evidence. Whatever your sector demands, we build it into the architecture from day one rather than relying on optional compliance add-ons.
Connected to what you already use. We integrate with your monitoring stack, your ticketing system, your communication platform, and your threat intelligence feeds through custom API work. No adapter layers, no manual data entry, no export-import cycles.
UK data residency by default. Self-hosted or UK-based cloud hosting, so your incident data stays on UK infrastructure. No ambiguity about GDPR compliance or data sovereignty.
Core modules and features
Every build is shaped around your specific setup, but these are the modules we typically deliver:
Alert ingestion and routing — Webhook endpoints that receive alerts from your SIEM (Wazuh, Graylog, Splunk), monitoring tools (Datadog, Prometheus, Grafana, New Relic, CloudWatch), or any system that supports webhooks. Intelligent deduplication and grouping so related alerts become a single incident rather than a flood of notifications.
Incident lifecycle management — A clear state machine: open, investigating, resolved, closed. Every incident carries severity classification (P1-P4), affected services, business impact assessment, and an owner. Custom fields for your specific context, such as customer name, revenue at risk, or regulatory category.
On-call scheduling and escalation — Rotation management with time-zone awareness, holiday handling, and fairness tracking. Escalation policies that can branch based on incident severity, affected service, customer tier, or time of day. Auto-escalation when incidents are not acknowledged within your defined thresholds.
Real-time collaboration — Integration with Slack or Microsoft Teams for dedicated incident channels. Status updates, acknowledgements, and notes flow between the platform and your chat tool in both directions. Works for Teams-first organisations, not just Slack-first ones.
Immutable audit trail — Every action, including creation, status changes, assignments, comments, and file attachments, is logged with a timestamp and user attribution. Records are append-only and cannot be edited or deleted. Designed to satisfy ISO 27001 (A.5.24, A.8.15), GDPR, and NIS2 audit requirements.
Compliance reporting — Automated reports showing incident counts, notification timelines, response metrics, and audit trail exports in the format your auditors expect. Supports the 72-hour GDPR breach notification window and the 24-hour NIS2 early warning requirement with tracking to prove deadlines were met.
Postmortem and remediation tracking — Structured post-incident review with root cause analysis, timeline reconstruction, and action item tracking. Each action item has an owner, due date, and status. No more postmortems where 60% of follow-up items quietly disappear.
Reporting and analytics — Dashboards showing mean time to respond (MTTR), mean time to investigate (MTTI), incident frequency by service and severity, escalation patterns, on-call overtime, and postmortem closure rates. Tailored to different stakeholders, from SOC managers to board-level reporting.
Mobile access — Respond to incidents on the move, including acknowledging alerts, updating status, and adding notes. Offline support for environments where connectivity is unreliable.
Runbooks and playbooks — A built-in library for standard operating procedures. Playbook automation can execute sequences of actions, such as collecting logs, capturing snapshots, notifying the security team, and creating tickets, based on incident type.
Role-based access control — Restrict incident visibility based on team, role, or incident sensitivity. Integrate with your existing identity provider (Active Directory, Okta, Azure AD) via SSO/SAML.
How the build works
Discovery and planning (2-3 weeks) — We interview your security and operations teams to understand your current incident response workflow, pain points, integration requirements, and compliance obligations. We document what needs to integrate, who needs access, and what the escalation rules look like in practice.
MVP build (8-12 weeks) — We start with the modules that matter most: alert ingestion from your primary monitoring tool, incident creation and tracking, on-call scheduling with basic escalation, chat platform integration, and audit logging. You get working software quickly and can test it against real incidents.
Phase two (4-8 weeks, if needed) — Advanced automation, SIEM enrichment from your CMDB or asset management system, conditional escalation based on business rules, SLO tracking, case management integration, and compliance report automation. This is usually funded as a separate project once the MVP proves its value.
Testing and deployment (2-4 weeks) — QA and user acceptance testing against your real infrastructure. We run test incidents through the system before go-live to catch configuration issues early.
Training and support (ongoing) — Role-specific training for on-call engineers, incident commanders, and compliance officers. Documentation, launch support, and ongoing maintenance with same-day response from our London team.
What it costs and how it compares
Custom development costs more upfront than signing up for a SaaS tool. But the total cost of ownership calculation often favours a custom build, especially as your team grows.
SaaS costs scale with headcount. A 50-person on-call team on PagerDuty runs £45,000-75,000 over three years, plus add-ons. ServiceNow implementations start at £250,000+ annually for enterprise deployments, with £50,000-150,000 in implementation consulting on top. Even lighter tools like Incident.io or Rootly run £15-25 per user per month, adding up quickly as you scale.
Custom build costs are front-loaded. A focused MVP runs £50,000-£120,000. A comprehensive mid-market build with advanced automation and full compliance support typically falls in the £150,000-£350,000 range. Ongoing support costs are a fraction of SaaS licensing and stay flat regardless of user count.
The crossover point. For most mid-market UK businesses with 30+ on-call staff, the custom build becomes cheaper than SaaS within two to three years. For larger teams, the saving is substantial. And you get a system that actually fits your workflows rather than one you have to work around.
What you avoid. No per-user licensing that punishes hiring. No surprise price increases at renewal. No vendor consolidation forcing you onto a different platform. No compliance gaps requiring expensive add-on modules.
Where custom incident management earns its keep
Financial services — FCA requires incident reporting within 72-96 hours for significant operational incidents. Map incident impact to critical business functions like payment processing and customer onboarding. Link fraud alerts to incident response workflows with the audit trail regulators expect.
Healthcare — Handle patient data breaches with reporting built for UK GDPR, the Data Protection Act, and CQC requirements. Track duty of candour obligations with escalation timelines. Maintain encrypted, access-controlled records with retention periods that satisfy both clinical governance and regulatory review.
Critical infrastructure and utilities — NIS2 requires a 24-hour early warning and 72-hour full notification for significant cybersecurity incidents. Coordinate outage response across operations and customer service teams. Link incidents to specific infrastructure assets for maintenance tracking.
Professional services — Protect client confidentiality with matter-specific access controls. Log security events without breaking legal privilege. Role-based visibility ensures only authorised staff can see sensitive incident details.
Manufacturing — Bring operational technology security into the same workflow as IT incidents. Track machinery incidents, near-misses, and safety violations with automated HSE escalation. Support non-conformance management and corrective action workflows for ISO 9001.
Public sector — Meet government security standards and Cyber Essentials requirements. Coordinate multi-agency or multi-department response with appropriate access controls. Maintain the evidence trail government auditors expect.
Software and SaaS companies — Integrate with your developer tooling, CI/CD pipelines, and cloud platforms. Detect failed deployments and coordinate rapid response across engineering and operations. Manage on-call for distributed teams across multiple time zones.
Education — Coordinate campus security responses across multiple sites. Route incidents to the right responder team based on location and incident type. Maintain safeguarding-compliant records.
Retail and e-commerce — Run incident response across physical security, digital security, and fraud teams in a single system. Escalate based on revenue impact and customer-facing severity.
Common Questions About Custom Security Incident Management Software
How does custom development cost compare to SaaS incident management?
SaaS platforms like PagerDuty charge £21-41 per user per month. For a team of 50 on-call staff, that is £45,000-75,000 over three years, and the bill grows every time you add someone. A custom build typically costs £50,000-£150,000 for a focused MVP, with ongoing support costs that stay flat regardless of team size. Most clients find the total cost of ownership is lower within two to three years, and you own the system outright.
What's the typical development timeline?
An MVP with alert ingestion, on-call scheduling, Slack or Teams integration, and audit logging takes 8-12 weeks. A more comprehensive build with advanced automation, multi-source SIEM integration, and full compliance audit trails runs 12-16 weeks. We deliver working software early and iterate from there.
Can you integrate with our existing monitoring and security tools?
Yes. We routinely build integrations with SIEM platforms (Wazuh, Graylog, Splunk), monitoring tools (Datadog, Prometheus, Grafana, New Relic), ticketing systems (Jira, Azure DevOps), communication platforms (Slack, Microsoft Teams), and threat intelligence feeds (MISP, VirusTotal). If your tool has an API or supports webhooks, we can connect it.
What compliance standards can the system support?
We build in support for UK GDPR (including the 72-hour breach notification requirement), ISO 27001 (immutable audit trails per A.5.24 and A.8.15), NIS2 (24-hour early warning and 72-hour full notification), Cyber Essentials, and sector-specific requirements like FCA incident reporting for financial services. Compliance is part of the architecture, not bolted on afterwards.
What happens if our SaaS provider shuts down or forces a migration?
This is a real risk. Atlassian is shutting down Opsgenie in April 2027, forcing customers onto Jira Service Management whether they want to move or not. With a custom build, you own the code and the data. No vendor can force a migration, change your pricing, or deprecate features you depend on.
Do you provide training for our team?
Yes. On-call engineers typically need about 30 minutes of training. Incident managers and commanders get a more detailed two-hour session covering timelines, escalation, and stakeholder communication. Compliance officers get focused training on audit trails, data retention, and reporting. We also provide documentation and ongoing support.
