On the lookout for the best DDoS Protection Software to counter malicious traffic on your network? This is what this post is all about. 

Since my business mainly operates online, any distributed denial of service attack (DDoS) that slows down communication with my clients is very damaging. Worse, they can either hold on to my services in exchange for a ransom.  

So I got my hands on DDoS mitigation software from reliable network service providers for my own peace of mind. 

Unfortunately, most DDoS platforms require a subscription but luckily most of the tools on the list are ones that offer free trials as well so that users can try them out and see if it works best for their use.

Over the years, I’ve tried several of them, and here are my top picks to help you decide which one to go for.

What Is The Best DDoS Protection Software?

If you’re in a hurry, check out my top 3 picks at a glance: SolarWinds Security Event Manager, Webroot DNS Protection, and Haltdos DDoS Protection Service.

1. SolarWinds Security Event Manager – Top Pick

Best DDoS Protection Software For Monitoring Event Logs  [Free Trial | $2,613/yr]

DDoS detection is just one aspect of SolarWind’s SEM. It uses a multi-layered approach to detecting these kinds of network security threats

This tool is designed to detect DDoS threats by collecting, correlating, and normalizing logs across your systems.

In particular, the Botnet Detection Tool catches unusual patterns that usually signal and attack. 

When a threat is detected, admins are automatically alerted to deploy responses to sever connections, block activities or shut accounts down.

Doing this does not require extensive custom scripts since configurations can be done by simply ticking checkboxes.

It also features a Threat Intelligence Feed, an automatically-updated tool to help detect DDoS attacks plus other forms of malware, spam, or viruses. 

Lastly, it comes with Forensic Tools where the repository of logs is leveraged in the post-breach investigations. 

This feature comes with a search function to filter for specific timeframes, specific IPs or accounts, or a combination of parameters. 

It leverages Boolean logic in its drag-and-drop UI to build queries easily without the need for grep or regex.

SolarWinds Security Event Manager Pricing Plan

solarwinds pricing

SolarWinds Security Event Manager has a 30-day trial version for all its features. After that, you have to choose between an annual subscription or a perpetual subscription. 

The pricing is mainly licensed by the number of nodes you need, not on the feature set. A node is any device (server, desktop, laptop) where event data is collected. 

It starts with a 30-node subscription. 

The paid versions can be a bit pricey given all the functionalities it includes so it’s best to take advantage of the free trial first. 

If you need a license for more nodes, you can contact sales support to get additional information.
