DDoS attacks overwhelm Magento stores with malicious traffic, which exhausts server resources and prevents real visitors from shopping or from accessing a website entirely. Magento 2 DDoS protection combines several security tools to detect and immediately block malicious IPs in Magento to reduce the risk.
While large-scale attacks often require hosting-level setup and configuration, Magefan Bot Blocker allows store owners to control abusive traffic directly from the admin through extensive DDoS settings, reCAPTCHA challenges, and traffic monitors.
This guide explains how DDoS firewall protection works in Magento, how to set it up and what other tools to use to protect Magento security.
What is Magento 2 DDoS Protection?
Magento DDoS protection is a set of security measures available directly in the Magento admin panel that detects, identifes, filters, and limits malicious traffic to reduce server load, store downtime or slow perfomance caused by large amounts of bots.
Example of the traffic monitor showing blocked countries, IPs, user agents, etc.
How DDoS Attacks Affect Magento Stores?
A large number of requests from bots consumes CPU, RAM and other server resources required for server-side processing, database queries and other operations on Magento storefronts.
Depending on the amount and type of traffic, DDoS attacks can affect different parts of Magento stores:
- Slow website performance: real shoppers may experience slow loading speeds or timeouts when server resources are exhausted.
- High server resource usage: a large number of requests increases CPU, RAM, and other resources on your server while consuming additional bandwidth.
- Unavailable pages: High traffic volumes can cause HTTP errors and make your entire storefront temporarily inaccessible.
- Checkout issues and lost sales: if bots target dynamic endpoints, it affects critical shopping steps and prevents customers from completing purchases.
Types of DDoS Attacks in Magento
Since DDoS attacks can target different layers of your infrastructure at different volumes, the protection depends on the type of attack.
- Volume-based attacks: their goal is to overwhelm your resources and bandwidth with large amounts of traffic. You need dedicated DDoS mitigation, a CDN or a Bot Blocker Extension to block these attacks.
- Application-layer attacks: send large amounts of HTTP requests to web applications or specific URLs. These attacks consume database resources even when overall bandwidth is not high.
- Bot-driven attacks: repeatedly request pages, APIs, search results, and resource-intensive endpoints. You can reduce these types of attacks by detecting and blocking traffic at the application level.
Important: it's best to handle large network-level attacks via a CDN or a hosting provider, but most of the time you can filter out abusive bot traffic using a dedicated Magefan Bot Blocker for Magento and the large feature set and traffic monitoring it provides.
Does Magento Have Built-in DDoS Protection?
Magento doesn't offer a complete DDoS protection service out of the box. While the platform includes multiple tools and features to address Magento security vulnerabilities, there is no tool to protect Magento from DDoS attacks.
Even though your store can be technically secure, attackers don't need to exploit vulnerabilities. It's enough to send enough requests to consume available server resources to degrade performance or cause timeouts.
That's why the most effective approach for most Magento stores is to use dedicated DDoS protection features or a CDN to target high volumes of abusive traffic. Magefan Bot Blocker helps to manage automated traffic directly from the admin panel via multiple tools like DDoS protection, Magento IP blacklist, CAPTCHA and others.
How to Know If Your Magento Store Is Under a DDoS Attack?
The main sign of Magento being under a DDoS attack is unusual traffic spikes combined with poor performance and repeated requests that can't be caused by legitimate shoppers. However, you should review your server logs, and traffic sources to determine whether the activity comes from malicious traffic or just some technical or configuration issue.
Look for the following signs when investigating unusual activity in Magento:
- Unexpected traffic volumes — a sudden increase in the traffic volume without any marketing, sales or other expected campaign running.
- Repeated requests to the same URLs — one or more pages receive an unusual amount of requests.
- Suspicious traffic sources — requests may come from unexpected locations (countries), unusual user agents or rotating IPs.
- Increased number of server errors — your store starts returning more 5XX errors or becomes unavailable.
- Long server response times — products, categories or other dynamic pages become too slow or time out eventually.
How to Enable Automatic Magento DDoS Protection?
You can enable automatic DDoS protection in Magento using the Magefan's , which provides both application- and architecture-level protections. The DDoS protection settings detect and help you control abusive automated traffic directly from the admin panel.
Instead of managing blocking rules at the server level and resorting to developers, store admins can configure available protection rules via the admin panel or rely on the existing pre-built settings.
Before enabling DDoS protection, make sure the Bot Blocker extension is installed and enabled. Then configure the available settings.
Step 1: Enable DDoS protection
Navigate to Stores > Configuration > Magefan Extensions > Bot Blocker > DDoS Protection and enable it. Then choose what to do when a certain IP crosses the request limit rules in the Action When Limit Is Reached dropdown.

You have the following options available:
- Send Email Notification (with ability to block via email) — the extension sends you a notification about a malicious IP with the option to block it via email.
Example of the DDoS protection email notification
- Block Immediately — the extension blocks the IP immediately.
- Block Immediately and Notify via Email — the extension blocks the IP immediately and notifies you about it via email.
- Require reCAPTCHA — requires CAPTCHA verification for a malicious IP.
Note: you need to configure the reCAPTCHA Keys under the reCAPTCHA section to use the Require reCAPTCHA option for DDoS protection.
Step 2: Configure request limits for DDoS protection
Magefan extension already comes with the pre-built settings for DDoS protection, according to the best security practices for Magento. But you can edit and change them to enforce stricter blocking.
Specify the number of requests a single IP can send within a specified period to be blocked or trigger the action specified above in the Max Requests per IP field. Then set a Subnet Block Threshold (× IP limit) to catch distributed attacks spread across multiple IPs.
Set the window in seconds that is used to count requests from a single IP in the Monitoring Window. Then define a temporary block time for IPs that exceed the request limit within a specified window in the Block Duration (seconds) field.
Finally, set how long to save the request log in the Traffic Monitor in the Request Log Retention (days) option.

Step 3: Monitor the blocked requests
Magefan stores all blocked traffic in the Traffic Monitor via System > Bot Blocker > Traffic Monitor. Here you can view the amount of blocked requests per specific periods of time along with a server load graph for the same period.

If you scroll down to the IP Overview grid, you can also see the paths those bots targeted, which countries, IPs or user agents they were from, and block them permanently.

Protect Magento from DDoS Attacks Without Blocking Real Users
The best way to protect Magento from DDoS attacks is to use multiple security layers rather than rely on a single tool. However, neither of them should create unnecessary friction or enforce restrictions for legitimate visitors.
Here's how to prevent Magento DDoS attacks without blocking real users:
- Allow trusted sources — whitelist verified IPs for store admins, developers, monitoring tools or other trusted addresses.
- Avoid using broad rules — don't block large IP ranges unless you're absolutely sure they need to, since it can affect real shoppers when attackers share infrastructure with real users.
- Review requested paths — pay attention to the URLs receiving high request volumes and block them with page restrictions rather than DDoS protection.
- Enforce restrictions gradually — Magefan Bot Blocker detects, monitors and blocks abusive traffic based on type of request, requested paths and user agents. Monitor and enforce restrictions based on types of abusive traffic gradually to keep your website functioning for legitimate users.
Note: you can combine DDoS protection features with IP blacklist or reCAPTCHA if bots are targeting specific pages or forms for an additional protection layer.
Example of the blocked IPs in the Magefan traffic monitor
The main goal of a DDoS attack on Magento is not to exploit the vulnerabilities of your store, it's to waste your resources to the point your website becomes unavailable for browsing or shopping.
Magento 2 Bot Blocker extension by Magefan can effectively detect and block huge amounts of unusual traffic coming from bots before it reaches your server, using the restriction rules directly in the admin panel. However, it is recommended to use DDoS protection together with other restriction settings like reCAPTCHA, rate limiting and country blocking in Magento.
