Plesk extensions included free in every StackRegent plan

Why there is nothing extra to buy#

A Windows hosting server needs the same building blocks whatever panel runs it: scheduled off-server backups, a WordPress manager, resellers, per-account limits, brute-force protection, spam and malware filtering. With Plesk, several of those come from its extension catalog or a higher edition, and some of the catalog's security and limit tools support Linux only. StackRegent ships them inside the panel, tests them with every release, and includes them in every plan, from one hosting account to unlimited.

The cards above list each one, what it does in StackRegent, and how Plesk handles it, as Plesk's own pages described it in November 2026. Sources are linked on the full comparison.

Plesk extensions included free, one by one#

Scheduled backups to cloud and SFTP storage#

Plesk's support article on backups says scheduled subscription backups to cloud or SFTP storage are a premium feature that needs Backup to Cloud Pro, and it lists Plesk for Windows among the platforms. StackRegent's Backup Manager schedules backups at server, client and subscription level, keeps the last N copies, and stores them on S3-compatible storage (Amazon S3, Wasabi, MinIO and others), SFTP with host-key pinning, or FTP/FTPS. It tests the connection before saving. Backups can be encrypted with DPAPI or a password; a password makes them restorable on another server. See backups.

WordPress Toolkit#

Plesk's WP Toolkit is free on Web Pro and Web Host; Web Admin gets a limited version and Smart Updates is sold separately. StackRegent's WordPress Toolkit is the same on every plan: install, scan for existing sites, update core, plugins and themes with a restore point saved first, apply hardening measures, back up, and create staging copies that can be pushed back to live.

Reseller management and unlimited domains#

According to Plesk's 2026 licensing guide, reseller management and unlimited domains come with the Web Host edition; Web Admin covers 10 domains and Web Pro 30. Every StackRegent plan has the reseller panel, and domains are never counted. Resellers get their own customers, plans and branding, and a reseller plan that is full refuses new accounts. See resellers and branding.

Per-account CPU, memory and disk I/O limits#

Plesk's Cgroups Manager supports Linux distributions only. On Windows, Plesk can cap the CPU of a dedicated IIS application pool and recycle it on memory. StackRegent puts each subscription's websites, PHP and scheduled tasks in a Windows job object with caps for CPU, memory, disk read and write speed, disk operations and process count, with limit-reached counters. See resource limits and isolation.

Brute-force banning that covers Remote Desktop#

Plesk's documentation marks Fail2Ban as Linux only. StackRegent's IP Address Banning watches Remote Desktop and Windows logons, the panel, FTP, SMTP, POP3, IMAP and password-protected directories, with banned and trusted lists and a log.

Spam filtering and virus scanning of mail#

Plesk Email Security lists Linux distributions only. StackRegent's spam filter combines SPF checks, DNS block lists, greylisting and an optional SpamAssassin service, and Microsoft Defender scans mail as MailEnable writes it to queues and mailboxes.

Malware scanning of websites#

Imunify360 is described on Plesk's site as security for Linux web servers, and its own price list starts at $12 a month per server. StackRegent keeps Microsoft Defender scanning the website folders, where uploaded web shells and infected plugins land, and excludes database files so scanning does not slow or damage them.

Included in both, for the record#

Some things are free in Plesk too, and we do not count them as savings: Let's Encrypt through the free SSL It! extension (which also offers wildcards, something StackRegent does not do yet), two-step sign-in through the Google Authenticator extension, and updates while the license is active. StackRegent includes Let's Encrypt for sites and the panel, TOTP two-step sign-in for administrators, and signed updates verified before install.

What StackRegent does not include#

Being clear about gaps matters as much as listing features. StackRegent has no site builder, no extension marketplace, no hosted Exchange, no ready-made billing module (billing systems use the REST API) and no Linux version. If your customers depend on one of those, weigh it against the list above.

How to check this for your own servers#

Write down the Plesk edition and extensions you pay for today, then open the pricing page and pick the StackRegent plan that matches your number of hosting accounts. The 10-day free trial has every feature on this page, so you can restore one Plesk backup and test the backups, limits and security tools with real data.
