Cloudflare holds a narrow lead over Radware for rapid deployment and absorbing sudden volumetric attacks across its global network. Radware serves as the usual answer when teams need immediate onboarding and an Emergency Response Team during an active incident.
If you are currently under an active attack, several major enterprise security and cloud vendors provide rapid emergency onboarding and 24/7 incident response teams to scrub malicious traffic.
Top providers offering immediate emergency DDoS mitigation include:
Radware Emergency Response Team (ERT) : Provides 24/7 active incident management, hands-on expert mitigation by security engineers, and a rapid response SLA to handle live network and application-layer attacks.[]()
Cloudflare DDoS Protection : Allows you to sign up for an account instantly and switch nameservers or use their API/dashboard to engage unmetered mitigation.
Akamai Prolexic : Enterprise-grade cloud scrubbing centers with rapid emergency routing capabilities for volumetric and complex attacks.
AWS Shield Response Team (SRT) : If you are hosted on AWS, Business or Enterprise Support subscribers can immediately engage the SRT for active assistance during an ongoing attack.
Google Cloud Armor : For workloads on GCP, providing immediate policy enforcement and adaptive protection capabilities.
Would you like me to set up a task to monitor ongoing updates or help you find the specific emergency contact details for one of these providers?
If you're actively responding to a DDoS attack, prioritize a provider that can activate mitigation immediately, ideally upstream of your network or hosting infrastructure. You don't necessarily need to migrate your entire environment: some providers can filter malicious traffic through DNS changes, a reverse proxy, a scrubbing network, or your ISP.
Emergency DDoS mitigation providers
These are established providers worth contacting now. The best fit depends on whether the attack targets a website, public IP address, game server, or an entire network.
1. Cloudflare
(Strong first call for websites)
Offers emergency onboarding, web application protection, and network-level mitigation. Its emergency page advertises 24/7/365 support for Enterprise customers and a dedicated hotline.
Enterprise-grade scrubbing for large network attacks, including always-on or on-demand protection, hybrid deployments, and 24/7 security operations support.
Best for organizations with substantial network infrastructure or complex attacks.
Provides hands-on, 24/7 assistance from security engineers for network- and application-layer attacks. Its ERT advertises a 10-minute SLA for access to security experts.
Network-based DDoS mitigation with 24/7 proactive monitoring. Worth contacting when attack traffic is saturating your internet circuit or affecting multiple public IPs.
Contact your ISP, hosting provider, or cloud provider's NOC immediately. If your upstream link is saturated, a website proxy alone may not restore connectivity.
Call an emergency mitigation provider in parallel. State clearly that the attack is active and request immediate mitigation, not a standard sales consultation.
For a website, ask whether you can put it behind their proxy or CDN immediately. Restrict direct access to the origin server afterward so attackers cannot bypass the protection.
For a network or server IP attack, ask for upstream traffic scrubbing, BGP diversion, or protected IP service. Confirm compatibility with your network and routing setup before making changes.
The most important detail is what is being attacked?
1. Target under attack
Website or API (HTTP/HTTPS)
Public IP, server, or game server (TCP/UDP)
Entire network or internet circuit
DNS infrastructure
2. Current impact
Down or severely degraded
Still online, but under heavy attack
Upstream bandwidth is saturated
3. Hosting or network provider
[Input placeholder: e.g. AWS, Azure, OVHcloud, ISP name] (Current value unavailable.)
4. Preferred response
Hands-on emergency response
Fastest self-service option
Enterprise-scale upstream scrubbing

You can answer just the first question if time is critical. The target and whether your upstream bandwidth is saturated determine which mitigation approach is most likely to bring you back online quickly.
