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.
