How to choose a defense system against DDoS attacks?
Selecting the right DDoS protection system depends on several factors: threat level, web resource characteristics, and budget. Let's take a look at the key parameters that will help determine the optimal solution.
1. Assess the threat level
Before choosing a defense system, it's important to understand exactly what attacks are threatening your site.
Easy Attacks - small attacks that cause a minor slowdown of the site.
Protection: Basic traffic filters, configuring firewall rules, using CAPTCHA.
Medium attacks - more organized botnet attacks that can cause short-term resource disruptions.
Protection: Use of cloud protection services, load balancing, limiting the number of requests from one IP.
Powerful attacks - attacks using thousands or millions of bots that can completely paralyze the server.
Protection: Specialized DDoS protection solutions such as Cloudflare, Akamai, Imperva or hardware firewalls, secure servers.
How do I determine the threat level?
Analysis of server logs - you can identify anomalies in the number of requests.
Use of monitoring services (Zabbix, Nagios) - helps to capture traffic spikes.
Consultation with hosting provider - Many providers can provide attack analytics.
2. Number of users and server load
When choosing a protection system, it is important to consider the average and maximum number of visitors to the site.
Small traffic (up to 10,000 users per month)
Average traffic (10,000 to 1,000,000 users per month)
High traffic (more than 1,000,000 users per month)
Important: if your site works with payment data or personal information of users, protection should be at the highest level.
3. Cybersecurity budget
The cost of defense against DDoS attacks can range from free solutions to premium services costing thousands of dollars per month.
Free or budget solutions
Cloudflare Free - basic protection, suitable for small sites.
Rate-limiting and firewall on the server - Configuring request limits.
Google reCAPTCHA - bot protection.
Medium budget ($10-500 per month)
Cloudflare paid plans (Pro, Business).
Sucuri - protection for WordPress and other CMS.
Use VPNs and proxy servers to filter traffic.
Large budget ($500+ per month)
Akamai Kona Site Defenderis one of the most powerful defense platforms.
Imperva DDoS Protection - enterprise solution.
Hardware firewalls (Fortinet, Cisco) - protection at the data center level.
Important:The most expensive solution is not always the best. The optimal protection depends on the specifics of your business.
4. Compatibility-with-hosting
Before choosing a protection, you should make sure that it is compatible with your server or hosting provider.
If you have shared hosting(e.g. Bluehost, GoDaddy)
Cloud solutions (Cloudflare, Sucuri) are an easy way to protect yourself.
It's important to check with your hosting provider if there are built-in security systems.
If you have a VPS / dedicated server
You can configure firewall, WAF (Web Application Firewall).
More advanced solutions are available, including hardware protection.
If you have a server in the cloud (AWS, Google Cloud, Azure)
Tip: Before purchasing protection, check with your hosting provider to see what solutions they support. Some companies already include basic protection in their tariffs.
