Stack Pro is a protective module for PrestaShop that restricts artificial and automated traffic at the server level through controlled modification of the .htaccess file. Blocking rules are executed before PHP and database queries are initialised, ensuring that unwanted requests are rejected at the HTTP stage.
The solution reduces CPU and MySQL workload, stabilises response time (TTFB), and minimises the impact of bot attacks, AI crawlers, and exploitation attempts (e.g., SQLi, XSS, brute-force). The module operates without interfering with the PrestaShop core and edits exclusively its own section within the server configuration file.
Information Parameters:
The module is designed for shops hosted on shared servers, VPS, or servers with CPU/RAM limits, where sudden bot traffic causes performance drops or account suspensions.
It is highly effective in B2B and B2C shops exposed to brute-force attacks, mass form scanning, automated stock level extraction, and competitor price monitoring.
Safe implementation of changes in .htaccess with automatic validation testing.
Sets of pre-defined security policies for quick deployment.
Manual blocking of IP addresses and ranges.
Automated management of .htaccess file copies.
Built-in server access log reader directly within the administrative panel.
No additional JavaScript and zero impact on page weight.
Blocking of mass queries that generate excessive load.
Rejecting unwanted traffic prior to executing MySQL queries reduces server response time (TTFB) and stabilises shop performance during traffic spikes.
Blocking artificial crawling and resource scanning aids in recovering the crawl budget and improves the quality of analytical data by eliminating empty sessions.
Best practices: Although the module is safe and creates its own snapshots, we encourage performing a standard backup of your firewall file (.htaccess) and the database before the first use. Furthermore, please note that the built-in access log reader is an optional and auxiliary feature – due to the varied configurations and restrictions of individual hosting providers, we cannot guarantee its operability on every server environment.
Legal & SEO Notice: The software is provided "as-is". This module directly interacts with the server's network traffic filtration logic (application layer). The purchaser (administrator) assumes full responsibility for any unwarranted modifications, manual IP scope blocks, or misconfigured traffic restrictions. Incorrect configuration may result in blocking legitimate customers and strictly preventing vital search engine crawler operations (e.g., Googlebot), potentially leading to severe SEO ranking drops or Google de-indexing. Always verify your website's accessibility via external performance tools, such as the fetch validation in Google Search Console, immediately after deploying new rules. The module creators and authors bear no liability for consequential damages, loss of profits, administrative configuration errors, or decline in overall search engine visibility resulting from the use of this product.

Filtering takes place at the .htaccess level before PHP and database queries are started. This allows malicious requests to be rejected earlier, which according to the description reduces CPU and MySQL load. The module does not add extra JavaScript to the storefront.
Safe Apply saves changes to .htaccess together with an automatic validity test. If an HTTP 5xx error is detected, the module restores the previous file version through a rollback mechanism. This is intended to reduce the risk of store downtime when deploying new protection rules and adjusting firewall settings.
Yes. The IP blacklist manager lets you add IPv4 and IPv6 addresses as well as entire CIDR ranges. Once the configuration is saved, the rules are immediately placed in .htaccess. This feature is intended for a quick response to specific unwanted traffic sources identified in event analysis and server logs.
The built-in server access-log reader displays IP addresses and bots rejected by the firewall, including 403 Forbidden responses. This makes it easier to diagnose malicious traffic from the Back Office. Availability depends on the configuration and limitations of the particular hosting environment, so it is an auxiliary feature.
Yes. Backup Manager creates an .htaccess snapshot before every rule modification. Administrators can use these backups when reviewing changes, while the retention mechanism removes obsolete snapshots to limit storage usage. The description also recommends making your own backup before using the module for the first time.
