Pillar 2 — Reliability & Resilience

Systems That Fail Gracefully. Or Don't Fail at All.

We deliberately break your systems in controlled conditions — before the real world does it for you. The outcome is validated availability, proven recovery, and business continuity you can quantify and commit to your customers and regulators.


What's at Risk Without It
$5.4B
$5.4B in losses across Fortune 500 from a single vendor update outage in 2024 — a resilience failure, not a software failure
$100K
Proportion of single outages costing over $100K has grown from 39% to 70% between 2019 and 2023 (Uptime Institute)
$2.2M
Banking and financial services suffer median outage costs of $2.2M per hour — 16% above the cross-industry average (New Relic FSI 2024)
Outages taking more than 48 hours to recover from have increased 4× since 2017 — DR strategies are outpaced by system complexity
What We Deliver

Chaos Engineering

Structured, hypothesis-driven failure injection — following the Netflix Simian Army model — to systematically expose every failure mode in your systems before customers do. GameDays built around your business-critical journeys.

High Availability

Verify your HA design actually delivers the "nines" you've promised — testing failover paths, load balancer behaviour, database replication lag, and active-active/passive configurations under real conditions.

Failover & Recovery Testing

Validate RTO and RPO commitments under realistic failure scenarios — not theoretical. Know your actual recovery time, not your planned one. Identify the gap between design intent and operational reality.

Disaster Recovery (DR) Baselining

End-to-end DR testing that validates your runbooks work in practice, your backup integrity is sound, and your recovery sequencing meets regulatory requirements. Regulators audit DR evidence — we create it.

SLA/SLO/SLI Engineering

Define, instrument, and continuously monitor Service Level Indicators and Objectives that are meaningful to your business. Error budgets that give engineering teams the freedom to innovate without breaching reliability commitments.

Continuous Resilience Monitoring

Ongoing resilience health checks — automated chaos experiments running in production-like environments, SLO burn rate alerting, and regular resilience reviews tied to your NFE maturity roadmap.

Business Outcomes We Deliver
99.99%
System availability achieved

Four-nines reliability validated through chaos engineering and HA architecture testing — the availability standard that 90% of enterprises now require.

75%
Reduction in unplanned outage incidents

Proactive failure injection identifies and fixes failure modes before they manifest as customer-impacting incidents.

10×
Faster failover and recovery

Tested, optimised runbooks and automated recovery sequences reduce recovery time from hours to minutes — validated in advance, not discovered under pressure.

£M
Regulatory penalty risk eliminated

Evidenced DR testing and availability proof satisfies FCA, PRA, DORA, and other regulatory resilience requirements — avoiding fines and enforcement action.

Pillar 3 — Security & DevSecOps

Security Is a Business Imperative, Not an IT Task.

The global average cost of a data breach reached $4.88M in 2024 — a 10% jump in a single year. For healthcare and financial services, average breach costs exceed $9M and $6M respectively. But the financial cost is only part of the story: 70% of breached organisations report significant operational disruption, and customer PII was compromised in nearly half of all breaches. Our Security & DevSecOps pillar moves security from a final-stage gate to a continuous engineering discipline — embedding vulnerability detection, compliance validation, and threat modelling into every layer of your delivery pipeline.


What's at Risk Without It
$4.88M
$4.88M average breach cost globally in 2024 — largest year-on-year increase since the pandemic (IBM 2024)

63%
63% of organisations deploy code without fully testing for security — creating a continuous production vulnerability backlog
What We Deliver

SAST & DAST in CI/CD

Static and Dynamic Application Security Testing integrated directly into your build pipeline. Vulnerabilities are caught at commit, not after deployment — eliminating the cost escalation of late-stage security fixes.

Vulnerability Assessment & Penetration Testing (VAPT)

Comprehensive VAPT across your application layer, APIs, infrastructure, and cloud configuration. We think like attackers — identifying exploitable vulnerabilities before they are exploited in production.

Infrastructure Security Review

Cloud configuration review, network segmentation audit, IAM policy analysis, and Kubernetes/container security assessment. Misconfigured infrastructure is a leading breach vector — we eliminate it systematically.

Code Review & Security Audit

Expert-led security code review targeting OWASP Top 10 vulnerabilities, authentication logic, cryptographic implementation, and injection risks. We review what automated scanners miss.

Threat Modelling

STRIDE and attack tree modelling applied to your architecture at design stage — the cheapest point to fix a security flaw. Threat modelling prevents security requirements being discovered in penetration testing.

Compliance & Regulatory Assurance

GDPR, PCI-DSS, HIPAA, ISO 27001, FCA, and PRA compliance validation built into your pipeline — producing the documented evidence that regulators demand and auditors expect.

Business Outcomes We Deliver
80%
Reduction in critical vulnerabilities pre-release

SAST/DAST in CI/CD pipelines catches critical and high vulnerabilities at code commit — eliminating the exponential cost of post-release remediation.

£0
Regulatory fines and enforcement actions

Evidenced compliance testing and documented security posture satisfies regulatory audit requirements across GDPR, PCI-DSS, FCA, and PRA frameworks.

$2.2M
Average breach cost reduction with AI-powered prevention

Organisations using security AI and automation in prevention workflows save an average of $2.2M per breach compared to those who don't (IBM 2024).

100×
Cheaper to fix at design than in production

Our shift-left security model catches issues when the cost to fix is a fraction of what it becomes when discovered in a production breach or pen test.

Common Client Questions
We already run pen tests annually. Why do we need DevSecOps?
Annual pen tests show your security posture on one day per year — and only after vulnerabilities have accumulated for up to 12 months. DevSecOps means every code commit is tested, vulnerabilities are caught within minutes, and your security posture is continuously improving rather than cyclically degraded.
How does this fit into an existing agile delivery process?
Our security engineers embed directly into your sprint teams — writing security stories, configuring pipeline tooling, and acting as the security champion. We don't slow delivery down; we build the guardrails that let your teams ship faster with confidence.
Can you produce evidence to satisfy our regulator (FCA/PRA/ICO)?
Yes. We produce compliance evidence packs — penetration test reports, vulnerability remediation records, audit trails from SAST/DAST tooling, and security posture assessments — formatted to the specific requirements of UK financial regulators, GDPR supervisory authorities, and PCI-DSS QSAs.
What security tools do you work with?
We are tool-agnostic but have deep expertise in SonarQube, Checkmarx, Veracode, OWASP ZAP, Burp Suite, Snyk, Prisma Cloud, Qualys, and Nessus. We work with your existing toolchain where possible and recommend best-of-breed alternatives where gaps exist.

Pillar 4 — Observability

You Can't Fix What you Can't See or Predict.

82% of organisations in 2024 reported MTTR for production incidents exceeding one hour — and this figure is trending in the wrong direction despite growing tool investment. The problem isn't a lack of monitoring data. It's a lack of actionable, business-aligned observability. The median ROI from a mature observability investment is 4× (New Relic 2024). Our Observability pillar — including our PEaS (Performance Engineering as a Service) model — transforms your operational data from a reactive fire-fighting tool into a proactive revenue protection system. Full-stack visibility that connects system health to customer experience and business outcomes.


What's at Risk Without It
82%
82% of MTTR durations exceed 1 hour in 2024 — up from 47% in 2021. The observability gap is widening as systems grow more complex
25–50%
Financial services engineering teams spend 25–50% of their time addressing outages — time not spent on innovation or growth
Without full-stack observability, FSI organisations detect and respond to high-impact outages 2× slower than those with mature observability (New Relic FSI 2024)
10+
Tool sprawl and siloed monitoring creates alert fatigue and blind spots — organisations often learn of major incidents from customers, not their own systems
What We Deliver

PEaS — Performance Engineering as a Service

Our APM-led managed service delivers continuous performance engineering without the overhead of building an in-house capability. A dedicated performance engineer embedded as a service, with full tooling and reporting included.

APM Setup & Optimisation

Deployment, configuration, and tuning of Application Performance Monitoring platforms — Dynatrace, New Relic, Datadog, AppDynamics — aligned to your business-critical transaction flows and SLOs, not just technical metrics

Full-Stack Observability

Unified observability across infrastructure (CPU, network, storage), application (traces, errors, latency), and user experience (Core Web Vitals, real user sessions) — providing a single source of truth for operational health.

SRE Support & Practice

Site Reliability Engineering support — from SLO definition and error budget management through to on-call runbook automation and post-incident review processes that create learning, not blame.

Real User Monitoring (RUM)

Instrument every actual user session — not synthetic proxies — to understand exactly what your customers experience across geographies, devices, and network conditions. Tie RUM data directly to conversion and revenue metrics.

Alerting & Runbook Automation

Intelligent alerting that fires on business impact, not technical noise. Automated runbooks that initiate remediation actions without waiting for human intervention — reducing MTTR from hours to minutes.

Business Outcomes We Deliver
85%
MTTR reduction — from 30min to 5min

Lenovo achieved an 85% MTTR reduction through full-stack observability, maintaining 100% uptime during their peak e-commerce period and directly protecting sales.

Median ROI on observability investment

New Relic's 2024 Observability Forecast found that 58% of organisations receive $5M+ in annual value from observability, with a median 295% ROI across all respondents.

60%
Reduction in downtime incidents

Proactive anomaly detection and predictive alerting identifies emerging issues before they breach SLOs — shifting from reactive fire-fighting to proactive prevention.

20%
Increase in conversion rates

Linking observability to real user experience data identifies performance degradations directly impacting conversion — and resolves them before they cost revenue.
