Technical Depth

Uncompromising Defense Layers

Defentra isn't just a blocklist. It's a multi-stage execution environment for network traffic, operating at a level that standard software can't reach.

NDIS Interception

Operates at the Network Driver Interface Specification level. Blocks packets before Windows Firewall even sees them.

Zero-Allocation DPI

Deep Packet Inspection using non-allocating memory structures. Zero garbage collection impact on your CPU performance.

Process-to-Port Mapping

Live resolution of port traffic to specific .exe files using kernel-mode callbacks. Precise per-app control.

O(1) Threat Lookup

Constant time IP verification. Whether we block 100 or 1,000,000 IPs, the performance impact remains exactly the same.

Technical FAQ

Can I cancel anytime?

These are one-time license purchases — not subscriptions. There is nothing to cancel. You own the license for the duration specified with no hidden recurring costs.

How do I activate my license?

After purchase, you receive a License Key via email. Simply enter it in the "Activation" tab of the Defentra app. Activation requires a one-time internet connection.

Conflict with other Antivirus?

Defentra is designed to run alongside Windows Defender and major AVs. Since we operate at the NDIS layer, we don't interfere with user-mode scanning engines.

Hardware Requirements?

Requires Windows 10/11 (64-bit). Defentra uses less than 32MB of RAM and 0.1% CPU idle. Compatible with all modern Intel and AMD processors.

Is it really a one-time payment?

Yes. We believe in ownership. You pay once, and you get protection and engine updates for the entire duration of your license with no further fees.

30-Day Money Back?

Absolutely. If you're not satisfied with the protection or performance, contact our support within 30 days for a full, no-questions-asked refund.
