<h3>Anti Spam Protection</h3>
Spam comments can damage your SEO, clutter your database, and waste moderation time. Titan provides automated spam protection that works in the background without interrupting real users.
Every comment is checked against a global spam database and evaluated using intelligent filtering rules. Suspicious comments are automatically marked as spam and hidden from public view.
Automatic spam comment blocking: Blocks spam comments in real time using a global spam database and intelligent filtering rules. Suspicious submissions are automatically marked as spam before they appear publicly.
Block spam comments without captcha: Protect your site from comment spam without forcing visitors to solve captcha challenges. Real users experience a smooth commenting process.
Save spam comments for review: Optionally store filtered spam comments in the moderation area so you can verify filtering accuracy and review blocked content.
Detailed spam processing logs: View logs of processed comments to understand how spam filtering works and monitor spam activity trends.
Privacy policy link integration: Display a privacy policy notice under comment forms to help with transparency and compliance requirements.
This ensures real visitors can interact freely while bots are filtered automatically.
<h3>Security Hardening Tools</h3>
Titan includes built-in security hardening options that reduce publicly exposed information and protect your website from common automated attacks.
Many bots scan websites looking for version numbers, exposed login patterns, weak passwords, or XML-RPC endpoints. Titan helps minimize those risks with configurable hardening controls that strengthen overall site security.
Strong Password Enforcement: Force users to create strong passwords based on the WordPress password strength meter. Weak passwords are a leading cause of account compromise. Enforcing strong credentials significantly improves login security and reduces unauthorized** access risks.
Hide Author Login: Attackers can attempt to discover usernames using author archive URLs. Titan prevents user enumeration by restricting access patterns that reveal valid login names. This reduces the effectiveness of targeted brute force login attacks.
Disable XML-RPC: XML-RPC can be abused for automated login attacks and pingback spam. Disabling XML-RPC reduces exposure to remote brute force attempts and limits unnecessary resource usage.
Hide Version Information: WordPress core and plugins sometimes expose version numbers in the source code. Attackers use this information to target known vulnerabilities. Titan removes version references to reduce fingerprinting risks.
Remove Version Query Strings: JavaScript and CSS files often include version query parameters. Removing these prevents attackers from identifying the exact WordPress or plugin version running on your site.
Remove Meta Generator Tag: The generator meta tag can reveal your CMS version. Titan removes it to reduce publicly visible system information and lower exposure.
Remove HTML Comments: Some themes and plugins output HTML comments that may expose structural details. Titan can remove these comments to limit unnecessary information disclosure.
Together, these security hardening options reduce your attack surface and strengthen your website without affecting normal functionality.
<h3>Activity Monitoring and Logs</h3>
Security is not only about blocking attacks. It is also about visibility and awareness.
Titan includes built-in monitoring tools that help you understand login behavior and security activity on your website.
Login Attempts Log: Track failed login attempts in real time. See which IP addresses are attempting access, how many retries were made, and when lockouts were triggered. This helps you evaluate brute force protection effectiveness.
Activity Logger: Monitor security-related events across your site, including login activity and system actions. Identify suspicious patterns before they escalate.
Error Log Viewer: View plugin-related errors directly from the dashboard. Diagnose configuration issues quickly without accessing server files.
Debug Information Export: Export diagnostic information when contacting support. This reduces troubleshooting time and speeds up issue resolution.
With proper monitoring and logging, you are not only blocking attacks but also gaining insight into how your website is being targeted.
<h3>PRO Anti Spam Features</h3>
Machine Learning spam detection: Advanced spam filtering powered by Machine Learning improves detection accuracy by analyzing behavioral patterns across large datasets.
Scan existing comments for spam: Identify previously approved spam comments and clean up your database.
Scan registered users for spam accounts: Detect and flag suspicious user accounts that may have been created by spam bots.
Enhanced background spam analysis: Apply additional invisible tests that improve spam protection without affecting legitimate visitors.

<h3>PRO Two Factor Authentication</h3>
Two-factor authentication adds an additional verification step beyond a password. Even if a password is compromised, attackers cannot access the account without the second authentication factor.
QR Code Setup: Scan a QR code with an authenticator app to activate two-factor authentication quickly and securely.
Manual Secret Key Configuration: Set up two-factor authentication manually if QR code scanning is unavailable.
Per User 2FA Management: Enable or manage two-factor authentication individually for specific users or roles.
Compatible with TOTP Apps: Works with popular authenticator apps such as Google Authenticator and other TOTP-compatible applications.
Two-factor authentication significantly strengthens login security for administrators and users.

Manual Backup Creation: Generate a backup instantly before making major changes to your website.

Titan Anti-spam & Security

Can't uninstall from the dashboard, requires sending data to 3rd party for the survey. Good that I have wp-cli or You can use FTP to uninstall.
NOT WORTH anymore.

I liked anti-spam a lot as an anti-spam plugin... But sadly now it has too many things, and I don't like it. With the free option it doesn't offer a complete security system, there are a lot of firewall options that can't be used, so it is too much for only an anti-spam plugin and quite complicated. So I changed to another one, because I also don't want it to collide with the other security plugin I use.

Too much things for an anti-spam plugin too few (on free) for a security one
