This Message Is Not for the IT Department
This message is for CEOs, board members, policy makers, and entrepreneurs whose decisions steer organizations. This information serves as an early warning system for cybersecurity threats that can cause major disruption without notice.
Many executives remain unaware of serious cybersecurity threats until their digital assets are compromised. Web DDoS attacks are affecting organizations across Kenya, Uganda, Nigeria, South Africa, Egypt, and globally impacting banks, hospitals, telecommunications companies, and government institutions.
What Happens During an Attack
According to Paul Njuguna, Lead Consultant at VILLASEZI Resources, during a typical attack scenario, your website slows dramatically, users cannot access applications, and your digital presence goes offline. Technical teams try to respond urgently, but the attack remains difficult to detect due to its nature.
What Exactly Is A Web DDoS Tsunami?
A traditional DDoS (Distributed Denial of Service) attack floods systems with excessive traffic until they fail. Web DDoS Tsunamis are more sophisticated, sending encrypted HTTPS requests that imitate legitimate customer traffic. This makes them very difficult to identify and mitigate as systems interpret the malicious traffic as normal user activity.
Where Did It Come From?
These cyber attack methods originated with political hacktivists during the course of the Russia-Ukraine conflict. The tools have since become available on dark web marketplaces, making them accessible to anyone with financial resources.
Recent attacks have affected East African organizations, including a Kenyan regional bank that experienced service disruption requiring days to restore.
How Do They Work and How Do You Stop Them?
Web DDoS Tsunami attacks use secure, encrypted HTTPS traffic with highly randomized patterns that blend with normal traffic patterns. This approach enables them to bypass traditional security measures while appearing as legitimate users.
Njuguna noted that effective solutions require AI-driven, behavioral-based defense systems rather than simply increasing server capacity. Systems like Radware employ machine learning to analyze authentic user behavior patterns and identify malicious traffic without blocking legitimate users.
Some of the top cybersecurity vendors that you can use to protect your organization from Web DDoS Tsunami attacks include:
- Radware – Global leader in AI behavioral protection with real-time attack mitigation
- Cloudflare – Excellent for edge protection, especially for SMEs and digital-first firms
- Akamai – Big-scale protection for enterprise and government-level platforms
- Imperva – Great for securing web apps and APIs
- Netscout Arbor – Trusted by telcos in Africa for deep network-level intelligence
These recommendations are based on analyst reports, CIO feedback, and field testing.
Given how connected the African business environment is, service disruptions have significant operational and reputational consequences. Cybersecurity requires executive-level attention and proactive measures rather than reactive responses.
