Convert an HTML site into Composr pages

LDAP support for corporate networks (Conversr only)

HTTP authentication: Tie into an existing HTTP authentication-based login system (Conversr only)

Proxying system: Programmers can integrate any existing scripts using our sophisticated proxying system (which includes full cookie support).

Minimodules and miniblocks: Programmers can port existing PHP code into Composr itself without having to strictly conform it to Composr's framework

Intuitive sitemap editor: Visually browse your site structure.

Menu editor: Our user friendly editor can work with several different kinds of menu design (drop-downs, tree menus, pop-ups, etc)

Zones (sub-sites): Organise your pages into separate zones. Zones can have different menus, themes, permissions, and content. They can also use a sub-domain.

Full structural control: Edit, move, and delete existing pages and modules.

Redirects: Set up redirects if you move pages, or if you want pages to appear in more than one zone.

Use Composr for clients and pretend you made it.

We ensure Composr is not hard-coded anywhere in the software where it would appear to an average user.

Compliance with major data protection legislation such as the GDPR

Allow members to download or purge their personal data from their profile. Set a limit on the number of days between downloads / purges to preserve server resources.

Also manage member data to a more technical degree in the Administration Zone.

Allow members to purge their data upon deleting their member account

Composr is careful to maintain important data (such as warnings or bans) when members request their data to be purged from their profile. But this data can still be purged on the admin side (in the Admin Zone).

Automatic generation of a basic Privacy Policy based on site settings and installed addons

Cookie Consent notice

Set declarations on the rules page which members must agree to on registration (or whenever they are changed) which are also stored in the database and e-mailed to the member as a written copy

Automatic detection, logging, notifying, and banning of hackers

2-factor-authentication: E-mail based 2-factor-authentication security when unrecognised IP addresses are used with certain usergroups (optional, Conversr-only).

Password strength checks: Enforce minimum password strengths based on length and use of upper / lower case, numbers, and symbols, and avoiding repeated characters (Conversr-only).

Architectural approaches to combat all major exploit techniques

A JavaScript framework that makes XSS attacks virtually impossible

Defence-in-depth: Multiple layers of built-in security.

Encrypted custom profile fields: Once set the CPF can't be read unless a key password is entered (Conversr-only, requires OpenSSL).

Extensive support and use of Content Security Policy (CSP)

Track failed logins and automatically ban brute-force attacks

HTML filtering

Protection against CSRF attacks: Forms and AJAX requests make use of randomly generated POST tokens

Root-kit detection kit for developers

• Blog vs. Non-Blog Posts: Choose to display blog posts only, regular news posts only, or both.
• Category Filtering: Limit results to specific news categories.
• Double Filtering: Apply a second category filter for a two-level categorization system (useful for large sites).

• main_rss block: Suitable for main content areas
• side_rss block: Designed for sidebars and smaller spaces

• Wider audience reach: Your content becomes accessible to those using feed readers and aggregators.
• Content repurposing: Other websites can incorporate your feed, increasing visibility.
• Increased traffic: Users discovering your content in feeds may visit your website directly.
• Staying on top: Those who use your RSS feeds will see when you post new news articles.

• title: The article title
• url: The article URL
• rss: The URL of your news RSS feed

• Visitor: Any one or device who visits the site but is not necessarily identified
• User: Any visitor who can be identified (e.g. has a session ID or tracked IP address)
• Guest: A user who is not logged in (in Conversr, they all share a special "Guest" ID / account)
• Member: A user who is logged in with a registered account on the website (they have a username and a member ID)
• Author: Specific to the authors addon, a profile of an entity (could be a member, individual, or even a company) who makes content for the site
• Subscriber: A user who receives newsletters from the site (they do not necessarily have to be a member)
• Submitter: A user who submitted content (usually a member, but could be a guest if the site is very open to submissions)
• Staff: A member who moderates any significant portion of the website
• Super-moderator: A staff member with global moderation capabilities
  • Moderator: Same as super-moderator but does not have those capabilities globally; they may only be able to moderate certain sections or content
• Super-administrator: A staff member with literally undeniable access to everything on the site
  • Administrator: Same as super-administrator but they might not have access to the most elevated of privileges such as accessing maintenance scripts

• Password Strength Setting: Administrators can set a minimum password strength requirement, forcing members to choose stronger passwords. Password strengths are calculated on a scale of 1-10 using algorithms that take into account letters (including case), numbers, symbols, repeat characters, use of dictionary words, and use of usernames / dates of birth / e-mail addresses.
• Forced Password Resets: Administrators can force specific members or all members to change their passwords upon next login, enhancing security in case of potential breaches.
• Expiring passwords: Administrators can require members to change their password after so many days.
• Encrypted CPFs: If the server has the OpenSSL PHP extension installed, specific CPFs (such as ones containing other passwords) can be encrypted to protect sensitive member data in case of a server compromise.
