DDoS or Distributed Denial of Service refers to a kind of cyberattack that focuses on amassing enough requests to a target server so that it shuts down. They are one of the biggest threats that enterprises and SMBs face today. DDoS attacks are by far the most common form of cyberattack, almost tripling in frequency in the last three years.
Cyberattacks are no longer a threat that focuses on just the largest enterprises out there. Instead, small and medium businesses are often targeted, as they’re likely to have fewer layers of protection set up.
Today, we’ll be going over the best tools for DDoS attack prevention; these automated tools make defending against DDoS attacks much more accessible and will do wonders to dissuade them from happening in the first place.

Indusface AppTrana is a WAF, DDoS, and Bot mitigation software. Its edge service bundle comes together with a patching service, Web Application Firewall, and vulnerability scanners.
The AppTrana is also excellent at absorbing volumetric attacks, with one of its main standout features being just how good it is at separating DDoS traffic and regular user traffic.
This tool utilizes its extensive database to set up rules and alert conditions for each website. It performs constant monitoring and detects botnets automatically, blocking their IPs to prevent the botnet from meddling with your websites. There’s also a built-in AWS to help you deal with layer three attacks.
AppTrana’s vulnerability scanner works by referencing OWASP’s top 10 threats, as well as the SANS 25 Vulnerability list. If it finds any vulnerabilities that fall into one of these two, it will automatically issue a patch to help with it. Furthermore, the tool has an SSL offloader and a content delivery network to help you accelerate your site’s performance.
The AppTrana comes in two different editions, with the above being contained in the Advance version, priced at $99 per protected application each month.

5. Sucuri Website Firewall
The Sucuri Website Firewall has DDoS attacks, and zero-day exploit prevention features. This tool looks at all of your HTTP and HTTPS traffic to stop malicious agents from getting to your site.
The tool uses geo-blocking to help you with blocking out DDoS traffic. This feature lets you completely stop traffic from the three countries with the most DDoS attacks. You can also whitelist specific IPs to help you communicate with your team or genuine visitors without blocking them.
As a website firewall, the Sucuri is relatively cheap compared to most dedicated tools on this list.

6. StackPath Web Application Firewall
StackPath is a DDoS protection tool and a WAP giving you layer 3, 4, and 7 protection. Layer seven protection uses behavioral algorithms to find and stop volumetric attacks. Its mitigation facilities can deal with HTTP, UDP, SYN flood, and other joint attack vectors.
To combat more significant attacks, the tool uses its capacity of 65Tbps to alleviate them. Since its capacity is larger than the most critical recorded DDoS attack, this feature is handy. The tool can also use its vast network of edge locations to block attacks from anywhere on the globe.
To help protect your websites, you can use its WAP to set up DDoS thresholds. This lets you dictate when the tool’s DDoS protection engine will react to a perceived attack. You can set up both burst and domain thresholds simply by setting several requests that you aren’t equipped to handle.

Cloudflare was designed with various DDoS and data breach attacks in mind. High request rates are combatted with rate limiting, while the tool uses CDN(Content Delivery Network) to ensure the network stays available.
Cloudflare has four different editions. Their Free version has the essentials for individuals or smaller businesses. Its Pro version costs $20 and has a WAP made for professional sites and blogs/portfolios. Their Business version has $200 a month, lets you set up customized WAF rules, and ensures a 100% uptime SLA.
