Consulting
WAF onboarding, bot mitigation, CAPTCHA integration, and cloud security architecture — delivered by engineers who've deployed these solutions for the world's largest financial institutions.
What We Deliver
WAF Deployment & Optimisation
We scope, configure, and deploy Web Application Firewalls for enterprise environments — including custom rule creation, change management, and ongoing tuning. Our team has hands-on experience onboarding services to WAF platforms at both the vendor and client side, including for top-10 global banks and payment processors.
Bot Mitigation
From credential stuffing and scraping to inventory hoarding and ad fraud, we design and implement bot management strategies tailored to your traffic profile. Our analysts have worked at both CDN-scale bot management platforms and dedicated bot detection providers, giving us insight into how automated threats operate and how to stop them.
CAPTCHA Integration
We help businesses integrate and optimise CAPTCHA solutions (including hCaptcha and reCAPTCHA) to balance security with user experience. Our team includes engineers with direct experience at a leading CAPTCHA provider, so we understand both the implementation and the detection side.
Cloud Security Architecture
Security advisory for cloud-native and hybrid environments across AWS, Azure, and GCP. We help organisations design secure architectures, review existing configurations, and implement best practices for identity, access, network segmentation, and data protection.
Incident Response & Threat Analysis
When an attack happens, we help you understand what occurred, contain the damage, and close the gaps. Our team has experience responding to attacks targeting some of the world's most high-profile web properties.
Ongoing Security Advisory
Long-term consulting engagements for organisations that need a trusted external security partner. We provide continuous posture assessment, vulnerability management guidance, compliance support, and strategic security planning.

Large Online Platform - Millions of Monthly Active Users
Challenge
Limited visibility into automated threats despite having CAPTCHA in place.
Service
CAPTCHA migration, signal analysis, threat correlation
A large online platform was relying on reCAPTCHA as its primary bot defence, but the security team had limited insight into what was happening behind each challenge. Bot traffic was getting through, fraudulent account activity was increasing, and the existing setup offered little in the way of actionable intelligence.
We led the migration from reCAPTCHA to hCaptcha — but the real value wasn't in swapping one CAPTCHA for another. It was in what we built around it.
Rather than treating CAPTCHA as a standalone checkpoint, we designed an integration that fed the technical signals from each interaction — fingerprint data, solve behaviour, session characteristics — into the client's broader security pipeline. We correlated these signals with internal data sources including login events, transaction records, and security logs, as well as known attack patterns and threat intelligence feeds.
This approach made it possible to identify relationships between seemingly unrelated events: a cluster of CAPTCHA solves from a particular fingerprint profile linked to a spike in failed login attempts, which in turn connected to a credential stuffing campaign sourced from a recently leaked database. Activity that had previously gone undetected was now surfaced, investigated, and blocked.
Outcome
42%
Reduction in automated fraud attempts
30%
Decrease in false positives
25%
Improvement in detection of coordinated bot activity
0%
No increase in friction for legitimate users
By establishing correlations across signals, internal systems, and attack behaviours, the company moved from simply blocking bots to understanding and stopping them with far greater precision.
A mid-sized European financial services group operating across multiple regulated markets
Challenge
Migrating from an underperforming legacy WAF to Akamai's platform without disrupting live payment and customer-facing services.
Service
WAF migration, Akamai onboarding, custom rule development, traffic analysis, change management
A European financial services group had been running a legacy WAF solution for several years, but the platform was increasingly falling short. Rule management was cumbersome, false positive rates were high enough that the operations team had started disabling protections on key endpoints to avoid customer impact, and the vendor's support responsiveness had deteriorated. The security team had lost confidence in the tool, and an internal audit flagged the WAF's limited coverage as a compliance risk ahead of their next PCI-DSS assessment.
The client selected Akamai as the replacement platform but had no in-house experience with Akamai's security product suite. They needed a team that could manage the full migration — not just the DNS cutover, but the rule translation, traffic profiling, and tuning work that determines whether a WAF migration succeeds or fails in production.
We started with a detailed audit of the existing WAF configuration: which rules were active, which had been disabled and why, what custom rules had been written, and where the known false positive problems were. This gave us a clear picture of what was actually protecting the applications versus what existed only on paper. We then mapped this against Akamai's Kona Site Defender rule sets, identifying where Akamai's managed rules provided equivalent or better coverage out of the box and where custom rules needed to be written from scratch.
The migration covered 34 web properties across three business units, each with different application stacks and traffic profiles. For each property, we configured Akamai's WAF policies in alert-only mode first, running them in parallel with the existing WAF for a minimum of two weeks. During this window, we analysed every triggered rule against real traffic to tune thresholds, whitelist legitimate application behaviours, and validate that the new rule set wasn't going to block real customers. Only after each property passed this validation phase did we cut over to active blocking and decommission the old WAF.
The most complex part of the project was handling the client's payment API endpoints. These carried transaction traffic subject to strict latency requirements and PCI-DSS controls. We worked closely with the client's infrastructure and compliance teams to design a cutover plan that included real-time monitoring dashboards, pre-agreed rollback triggers, and a dedicated war room for the switchover window. The payment endpoints migrated cleanly with no customer-facing impact.
Outcome
34 web properties fully migrated from legacy WAF to Akamai over 10 weeks
False positive rate reduced by 68% compared to the previous WAF configuration
Zero unplanned downtime or customer-impacting incidents during migration
15 previously disabled security rules replaced with properly tuned Akamai equivalents, closing coverage gaps identified in the internal audit
Client achieved PCI-DSS compliance at next assessment with the new WAF architecture cited as a significant improvement
The client's security team noted that for the first time, they had confidence in their WAF — not just as a compliance checkbox, but as an active defence layer they could trust to block real attacks without breaking legitimate traffic.
A retail gaming company serving over 2 million online customers
Challenge
Sustained credential stuffing attacks causing account lockouts, customer complaints, and potential account takeover.
Service
Bot mitigation, WAF tuning, fingerprint analysis, incident response
A gaming company was experiencing a persistent credential stuffing campaign — automated attacks using stolen username/password combinations from third-party data breaches to attempt mass login. The attacks were causing thousands of legitimate customer accounts to be locked due to failed login thresholds, generating a surge in support calls, and creating real risk of account takeover for customers who reused passwords.
The bank had a WAF in place, but its rate-limiting rules were too blunt: they caught some bot traffic but also blocked legitimate customers, and sophisticated attackers were rotating IPs and distributing requests to stay under thresholds.
We took a layered approach. First, we deployed advanced fingerprinting analysis at the login endpoint to identify bot sessions based on behavioural and device signals rather than just IP reputation. Second, we restructured the WAF's rate-limiting rules to use composite keys — combining IP, session fingerprint, and user-agent patterns — so that distributed attacks couldn't evade detection simply by rotating source addresses. Third, we integrated CAPTCHA challenges that triggered dynamically based on risk score rather than applying universally, keeping friction low for legitimate customers.
Finally, we worked with the companies fraud team to build a correlation layer between blocked login attempts and known compromised credential databases, enabling proactive outreach to customers whose credentials had been exposed.
Outcome
91% reduction in successful credential stuffing attempts within the first two weeks
Customer account lockouts decreased by over 80%
Support call volume related to login issues dropped significantly
Proactive customer notification programme identified and alerted over 15,000 at-risk accounts
