● THE CHALLENGE
Why it was hard.
Repeated DDoS and intrusion attempts shook the service, but the team kept blocking ad hoc without pinning down the cause. Defense was scattered, so the same attack came back in a new shape. They needed a system, not one-off blocks.
Constraints
- Respond live — keep availability
- Root cause first
- A standing system that prevents recurrence
● OUR APPROACH
What we did.
01
Incident analysisTrace logs, traffic, and intrusion paths to the root cause
02
Defense designWAF, rate limiting, network boundaries, least privilege
03
Automated detection·responseAnomaly detection with automatic blocking and alerts
04
Standing operationsDrills and regular reviews keep the system sharp
● OUTCOME
Outcome.
Ad hoc blocking became a standing defense that starts from root cause. We built boundaries and detection so the same attack can't recur, and it has run incident-free since — detecting and responding to attacks 24/7.
