DDoS Protection

Full story First attack – The first attack was held on November 10th, 2025, at about 8:30 am, and alerts began to be received regarding the detection of attacks on the Hosting customer’s IP addresses and the upstream ISP addresses. The system identified an attack on about 500 IP addresses that included several vectors of attack, to 2 destination ports (0,443) with a capacity of 11.3 GB of traffic that was blocked by FlowSec’s system.   The attacks lasted for about 1 hour, while the Packet Per Second Traffic reached about 1.3M PPS. The attack protocols were ICMP, UDP, and…

In the evolving landscape of cybersecurity, Internet Service Providers (ISPs) hold a unique strategic position. They operate the infrastructure where attacks first appear, they serve thousands of organizations simultaneously, and they are responsible for maintaining national-scale connectivity. As attacks become more sophisticated and dynamic, ISPs can no longer rely solely on automated mitigation — they need deep, real-time understanding of how their networks behave. This is where advanced operational intelligence tools — similar in purpose to Flow Assistant — are reshaping ISP cyber defense strategies. These tools give Network Operations Centers (NOCs), security teams, and engineers unprecedented visibility into traffic…

Full Story On October 5th, 2025, at about 10:30, alerts began to be received regarding the detection of attacks on the SMB’s customer IP address. The system identified an attack that included several vectors of attack, with a capacity of 280 Gbps of traffic that was blocked by FlowSec’s system. The attacks lasted for more than 5 hours, with an increase in the peak volume of the attack to about 6 GB, 10 GB, and up to 13.8 GB, while the Packet Per Second traffic reached from about 400K up to 1.3M PPS. The attack protocols were TCP (ACK, PSH)….

For years, Internet Service Providers (ISPs) were viewed primarily as connectivity providers — responsible for stable bandwidth, uptime, and network infrastructure. Cybersecurity was considered “someone else’s job”: enterprises installed firewalls, SMBs relied on basic antivirus tools, and cloud vendors offered optional add-on protections. But as modern cybersecurity threats grow more aggressive and complex, a fundamental shift is taking place: customers now expect their ISP to be a frontline security partner, not just a bandwidth supplier. This transformation did not happen overnight. A combination of evolving threats, market failures, and technological innovation has made the ISP’s role in cybersecurity not only…

What a 700% Cyberattack Surge Says About the Future of DDoS Defense Strategy for ISPs This past week, Israel Hayom (a major Israeli news outlet) reported a 700% increase in cyberattacks targeting Israeli networks, including a sharp rise in DDoS (Distributed Denial of Service) attacks, which aim to overwhelm and disable critical infrastructure and online services. Internet Service Providers (ISPs), Government websites, critical infrastructure, and many business customers all saw a dramatic spike. The volume alone raised alarms. But the bigger story is what this tells us about the evolving role of ISPs in national and global cybersecurity. A New…

5 Industries Most Vulnerable to DDoS Attacks Distributed Denial of Service (DDoS) attacks are among the most disruptive cyber threats, capable of overwhelming networks and services with malicious traffic. These attacks target industries that depend heavily on digital infrastructure, exposing vulnerabilities and causing financial losses, operational disruptions, and reputational damage. Here’s a closer look at the five industries most vulnerable to DDoS attacks, their challenges, and effective mitigation strategies.
