Increasingly, business is done online. This increases the risk of exposure to costly service interruptions caused by cyberattacks. Distributed Denial of Service (DDoS) attacks have emerged as one of the most common and impactful attack vectors aimed at business networks.

Today, DDoS attacks account for 40% of all cybersecurity incidents, with some organisations facing multiple attacks per day. With the average throughput of volumetric attacks rising by over 3X in the last decade, DDoS prevention has become essential for any organisation that relies on its network infrastructure to do business.

Business Consequences of DDoS Attacks

DDoS attacks can have a range of business consequences, most commonly including:

Downtime of key systems and applicationsDisruption of internal and partner operations
Consumption of IT time and resourcesEmergency recovery costs

Attacks disrupt your organisation’s network. Every second that passes without restoring normal operations can lead to mounting costs, user dissatisfaction, and missed opportunities. Stable and reliable network uptimes are critical for meeting SLAs and KPIs.

What is DDoS Detection?

Detection is the first phase of protecting against network and protocol attacks. Organisations need technology that can quickly and accurately detect malicious traffic and apply the appropriate mitigation strategies.

FastNetMon is a versatile DDoS Detection tool, sensitive to a range of DDoS attack types:

  • Flood attacks via UDP, TCP, ICMP
  • IP Protocol attacks via fragmented packets
  • TCP Protocol attacks via SYN, SYN-ACK, and FIN floods
  • Amplification attacks via NTP, SNMP, SSDP, DNS, GRE, charges, and more
  • Multi-vector attacks using a combination of techniques

FastNetMon can operate at scale without slowing down thanks to a high-performance real-time traffic processing engine implemented in C++. It supports various traffic telemetry protocols, including NetFlow, IPFIX, sFlow, and SPAN/port mirror (e.g., Amazon and Google VPC Flow Logs).

How Does FastNetMon Detect Malicious Traffic?

FastNetMon supports a broad range of capture engines, including port mirroring, NetFlow, sFLOW, and IPFIX, which feed it information about incoming traffic. It can detect incoming attacks quickly based on increases in bandwidth usage, packet per second (Pps) count, and flow count. It also enables network engineers to alter each parameter based on past attack profiles.

FastNetMon gives network administrators full control over the detection and mitigation process, allowing them to design, configure, monitor, and manage DDoS defences that suit their organisation’s needs, budget, and network hardware.

With 2-second detection, FastNetMon responds to attacks the instant it receives traffic information from your network equipment (routers, switches, firewalls).

Protect Your Growing Attack Surface from DDoS Attacks

Any device or software asset accessible via the Internet is part of your attack surface. The more Internet-connected software and hardware assets you have, the larger your attack surface. Digital transformation initiatives, in particular, result in a huge expansion of an organisation’s attack surface and spiralling cyber risk.

As your attack surface grows, it becomes more likely that you’ll be targeted with DDoS attacks—and their potential impact also grows. Being able to mitigate DDoS attacks is crucial, and your DDoS protection program should evolve as your network infrastructure grows.

FastNetMon is highly scalable and supports a range of DDoS mitigation services and strategies.

Mitigate DDoS Attacks with FastNetMon

FastNetMon is a complete network security solution that offers a full range of capabilities to monitor and protect your network. Beyond detecting attacks, FastNetMon features advanced DDoS mitigation capabilities to limit damage and disruption to your organisation and help you restore normal operations promptly.

Anti-DDoS Mitigation Strategies

We believe every organisation should be free to develop an anti-DDoS strategy that supports its needs, budget, and risk tolerance. To make this possible, FastNetMon enables organisations to automate DDoS mitigation strategies, including:

BGP BlackHole Automation

FastNetMon is compatible with all BGP implementations and bundled with BGP Unicast and BGP flow spec (RFC 5575). If an attack is detected, BGP will automatically be triggered to block or divert traffic from an attacked host. FastNetMon rapidly blocks sophisticated attacks, ensuring your network’s safety and uptime.

flowspec ddos mitigation

Flowspec DDoS Mitigation

Keep your legitimate traffic flowing while blocking malicious traffic using BGP FlowSpec-capable routers. Maintain business operations, manage customer experiences, and minimise downtime-related capital expenses while protecting your network and filtering malicious traffic.

Blocklist Filtering

Blocklist filtering is a routing-level anti-DDoS technique that blocks traffic originating from specified senders. This approach is highly effective for mitigating DDoS activity from sources known to be malicious and can also disrupt other threats, such as malware, e.g., by blocking communications with external C2 infrastructure. FastNetMon ingests data from threat feeds and updates the master blocklist with new and defunct threats in real time.

ddos scrubbing center

DDoS Scrubbing Center Diversion Automation

Diverting malicious network traffic to a scrubbing centre is one of the most effective ways to mitigate a DDoS attack. Malicious traffic is routed away from your network, allowing you to filter traffic while reducing your network load. FastNetMonsupports all scrubbing centres and can automatically reroute traffic when it detects an attack.

Traffic Visibility

FastNetMon maintains in-depth traffic data within an efficient storage system. This data is retained for years and allows you to instantly request customisable reports to get an in-depth understanding of your network’s traffic during any period.

Why Every Business Needs DDoS Protection

Maintain SLA-backed guarantees

Maintain Customer Satisfaction

Predictable Business


Breaching SLAs can lead to a loss of customer trust and increase the risk of financial losses and litigation. For service providers like ISPs, data centres, and cloud providers, DDoS protection can help protect your business by maintaining high service levels.

Successful attacks directly impact your bottom line—and they also cause indirect damage via frustrated and unserved users. Unresponsive, unavailable, or slow consumer-facing portals may be the result of a DDoS attack.

For mobile operators, ISPs, and VoIP operators, the network IS the business. Interruptions or unpredictable traffic patterns may disrupt your ability to conduct business. In this case, DDoS attacks directly threaten your bottom line.

Improve Key Incident Response Metrics

Prevent Data Breaches

Digital Forensics

Many businesses underperform on metrics like Mean Time To Detect and Respond (MTTD/MTTR). These metrics directly correlate with damage suffered due to an attack, especially when it comes to DDoS.

DDoS attacks are often a cover for more targeted attacks. Cybercriminals exploit this opportunity to access your data, exfiltrating or ransoming mission-critical or consumer information.

Determining a cyberattack’s exact course and timeline can help identify weak points in your network infrastructure. Network visibility and reporting capabilities support hardening against future incidents, as well as damage mitigation and remediation.
