Real security, real results

The Challenge

Layer 7 DDoS attacks were overwhelming the application server twice a week. The client had a generic Cloudflare setup with no custom WAF rules. Payment fraud attempts via Stripe were manually reviewed with no automated detection. PCI DSS compliance was at risk.

Our Approach

• Deployed a multi-layer WAF with custom rule sets tuned to their application traffic patterns
• Implemented rate limiting, bot detection, and IP reputation filtering at the edge
• Conducted a full Stripe Payment Protection audit — identified 3 misconfigured webhooks and 2 unauthorized API keys
• Set up AI Watchdog with <90-second alerting on anomalous payment patterns

The Result

Zero DDoS-related downtime since deployment. Stripe webhook attacks stopped at the edge. The client saved an estimated €18,000/year in fraud-related chargebacks. PCI compliance score went from failing to 100%.

The Challenge

An internal audit revealed that the healthcare portal's Ubuntu servers had SSH password authentication enabled, no firewall rules, and outdated kernel parameters. Patient data was transmitted without full encryption in transit. The organization faced potential GDPR fines of up to 4% of annual revenue.

Our Approach

• Full OS hardening audit — 23 critical findings identified and remediated
• Deployed UFW firewall with default deny policy and service-specific allow rules
• Configured full-disk encryption and TLS 1.3 exclusively
• Implemented Fail2ban with custom jails for the healthcare application
• Deployed AI Watchdog with weekly compliance reporting

The Result

Passed subsequent GDPR audit with zero findings. 100% of patient data now encrypted in transit and at rest. Server hardening score improved from 34% to 94%. The CEO reported a measurable increase in patient trust signals.

The Challenge

The startup had 50+ microservices running on a single flat network segment. A compromise of any service meant full lateral movement. No intrusion detection, no network monitoring. Investors flagged security architecture as a risk factor for the Series A round.

Our Approach

• Designed and implemented network segmentation with 4 isolated zones (public, private, data, management)
• Deployed Suricata IDS/IPS with custom rules for the FinTech application stack
• Installed RootCrak Internal Network Agents on every segment for continuous visibility
• Set up AI Watchdog with real-time alerting and weekly executive reports

The Result

Series A due diligence passed with no security objections. 100% lateral movement blocked by segmentation. The CTO reported having "better visibility into our network than any previous employer." Incident response time reduced from 4+ hours to under 90 seconds.

The Challenge

The law firm had zero email authentication configured. Anyone could spoof a partner's email address. Three BEC attempts in the prior quarter had resulted in one near-miss wire transfer of €240,000 that was caught manually. The managing partner described their email security as "a paper shield."

Our Approach

• Configured SPF, DKIM, and DMARC from the ground up with quarantine policy and monitoring
• Deployed anti-phishing training for all 200 employees with simulated campaigns
• Implemented DMARC reporting and analysis for continuous improvement
• Set up internal network monitoring to detect compromised workstations

The Result

Zero successful BEC attacks since deployment (12+ months). DMARC went from absent to enforcing (p=quarantine) with 99.97% legitimate email delivery. The firm's cyber insurance premium was reduced by 18% following the security improvements.

The Challenge

The manufacturing plant had been running the same SCADA setup for 12 years. IT and OT networks shared a physical switch in the server room. A single misconfigured firewall rule allowed RDP from the sales department to the PLC management interface. Production downtime cost €12,000 per hour.

Our Approach

• Conducted full penetration test of both IT and OT networks — identified 21 critical findings
• Designed and implemented true network air gap between IT and OT with one-way data diodes for monitoring
• Deployed ICS-specific monitoring agents (non-intrusive, read-only) on the OT network
• Conducted zero-day research on the SCADA platform — discovered and disclosed 2 vulnerabilities

The Result

Zero production interruptions during the entire engagement. All 4 IT-to-OT attack paths closed. The 2 zero-day vulnerabilities were patched by the vendor within 30 days. The plant's cyber insurance was renewed with no exclusions for OT systems.

The Challenge

The SaaS platform was processing sensitive customer data across 50 EC2 instances, 10 microservices, and 3 AWS regions. Security monitoring consisted of "checking CloudWatch when something breaks." Multiple CVEs in their application stack went undetected for months. The CTO described their security posture as "hope-based."

Our Approach

• Deployed RootCrak Internal Network Agents on all 50 servers for continuous vulnerability scanning
• Implemented AI Watchdog with automated CVE correlation and priority scoring
• Set up weekly automated reports with executive summaries for the leadership team
• Integrated AWS CloudTrail and GuardDuty logs into the Watchdog for unified visibility

The Result

3,500+ CVEs identified and remediated in the first month. Mean time to detection dropped from weeks to under 90 seconds. The CTO reported that the AI Watchdog "caught things our DevOps team had missed for over a year." The platform maintained 100% uptime throughout.
