Terms of Service

The terms governing your use of the ThreatListPro IP blocklist service, operated by CalMax Systems.

1. Acceptance of Terms

By accessing or using ThreatListPro (the "Service"), you agree to be bound by these Terms of Service ("Terms"). If you do not agree to these Terms, you may not use the Service. These Terms apply to all users, including free trial users and paid subscribers.

2. Service Description

ThreatListPro provides a curated IP blocklist designed for VPN brute force protection. The Service delivers a URL-based list of IP addresses that can be imported into firewalls as an External Dynamic List (EDL). The blocklist is updated weekly and is intended to help organizations block known malicious IP addresses at the network perimeter.

The Service is provided on an "as-is" basis. While we make every effort to ensure accuracy and reliability, we do not guarantee that the blocklist will prevent all attacks or that it will never produce false positives.

3. Account and API Key

Upon subscribing, you receive a unique API key that grants access to the blocklist. You are responsible for keeping your API key confidential. You may not share, sell, or redistribute your API key or the blocklist data to third parties. Each subscription is for use within a single organization.

To the maximum extent permitted by law, CalMax Systems and ThreatListPro shall not be liable for any indirect, incidental, special, consequential, or punitive damages, including but not limited to loss of profits, data, or business opportunities, arising from your use of or inability to use the Service.

The Service is a supplementary security tool and should not be relied upon as your sole method of network protection. We are not responsible for any security incidents, data breaches, or unauthorized access that may occur despite the use of our blocklist.

Our total liability for any claims arising from the Service shall not exceed the amount you paid for the Service in the 12 months preceding the claim.

7. Privacy

Your privacy is important to us. We collect minimal data necessary to operate the Service. For full details on our data practices, please review our Privacy Policy.

8. Intellectual Property

The ThreatListPro name, logo, website content, and blocklist data are the intellectual property of CalMax Systems. Your subscription grants you a limited, non-exclusive, non-transferable license to use the blocklist for your internal network security purposes only.

9. Termination

We reserve the right to suspend or terminate your access to the Service at any time if you violate these Terms or engage in activity that we determine is harmful to the Service or other users. Upon termination, your API key will be deactivated and you will no longer have access to the blocklist.

10. Changes to Terms

We may update these Terms from time to time. If we make material changes, we will notify existing subscribers via the email address associated with their account. Continued use of the Service after changes take effect constitutes acceptance of the updated Terms.
