NETSECPROTECT Get started

Next generation desktop security for Windows

Nothing reaches your apps unfiltered.

Think of it as a harbor, not a doorman. Every connection is boarded and inspected before it's ever allowed near your system — not caught afterward, once it's already inside.

Built for BitTorrent traffic

Made to run alongside qBittorrent, not against it

Torrenting isn't client-server traffic. A single active torrent means dozens to hundreds of direct, simultaneous connections to strangers' machines — no server in the middle, no way to just block "unknown" traffic without breaking your own swarm. Most security software either ignores that traffic entirely or treats all of it as suspicious. NSP does neither.

Downloading

Peers get inspected like anyone else

Every peer connection is examined the same way any other traffic is — malformed pieces, protocol abuse, and connections that don't behave like real BitTorrent traffic get caught, without you babysitting a blocklist.

Seeding / uploading

An exposed seed isn't an afterthought

A long-running seed is one of the most exposed things a machine can do — always-on, always-connectable. Upload traffic gets the exact same inspection your downloads do, not a lighter pass because it's "just seeding."

qBittorrent-aware

Your swarm isn't mistaken for an attack

NSP already knows what real qBittorrent connection churn looks like, so a healthy swarm of a hundred peers doesn't get treated like a burst attack the moment a big download starts.

Antivirus was built to catch files. Modern threats don't need one.

Traditional antivirus asks one question: does this file match something already known to be bad? That worked when malware arrived as an attachment and sat still on disk waiting to be scanned. It doesn't work against threats that never write a file at all, that change their signature on every delivery, or that simply borrow a connection your own applications already use.

NSP doesn't wait for a file to scan. It examines every connection in and out of the machine — every one, both directions — in real time, using several independent methods at once. A threat only has to slip past all of them, not just one.

Signature

Known threats, matched instantly

Traffic patterns already tied to known malware families and attack tools are recognized and blocked the moment they appear. The baseline every security tool should still do — just not the only thing NSP does.

Deep packet analysis

Looks inside, not just at the label

A packet's headers can claim to be almost anything. NSP inspects what's actually inside the payload — the only way to catch traffic that's deliberately mislabeled to slip past filters that only check ports and addresses.

Encrypted traffic

TLS doesn't mean invisible

Most malicious traffic today travels encrypted specifically because most security tools can't see past it. NSP looks at what's actually happening inside a TLS session instead of trusting the lock icon on faith.

Protocol conformance

Traffic has to act like what it claims to be

A connection announcing itself as one protocol but behaving like another — a common way to smuggle command-and-control traffic through a port that's normally allowed — gets caught on the mismatch alone.

Intent

What a connection is trying to do

Beaconing on a timer, bursts with no legitimate trigger, a connection that doesn't match how an application of its kind normally uses the network — the pattern gives it away even when every individual packet looks clean on its own.

Behavioral baseline

Catches what's never been seen before

Signature matching can only stop what's already known. NSP also learns what normal looks like on your machine, so something brand-new with no signature yet still stands out the moment it acts differently.

A harbor that inspects before it lets anything dock

Picture your machine as a harbor. Nothing reaches the docks without passing inspection first — and the checkpoints don't trust each other blindly. If one goes quiet, the ones behind it don't wave everything through.

Checkpoint 01 Outer breakwater

Boarded before you ever see it

Every connection is stopped and inspected at the harbor mouth, well before it's anywhere near the docks — not waved through and dealt with later, once it's already tied up alongside everything you're running.

Checkpoint 02 Inner seawall

A second, independent gate

A separate checkpoint closer to the water itself, so a single blind spot at the outer gate is never the only thing standing in the way.

Checkpoint 03 Customs house

Opens what doesn't match its manifest

Cargo that claims to be one thing but is packaged like another gets opened and checked — the same instinct that catches a shipment traveling under false papers.

Checkpoint 04 Harbor patrol

Watches behavior, not paperwork

Patrol boats don't check documents — they notice loitering, circling, and signaling patterns that give away trouble long before any single act would.

Checkpoint 05 The harbormaster never sleeps

Someone is always on watch

If the watch officer is knocked out, backup is standing by and takes over within moments — and the gate itself doesn't quietly swing open just because no one appears to be looking.

Updates are authenticated, not just downloaded

No API key living in a config file somewhere. No password that can leak in a breach and get replayed against every install at once.

Every installation generates its own private key on your machine and only ever sends a certificate signing request outward — the private key never leaves your disk, not even during enrollment.

The update service signs back a certificate scoped to that one install. From then on, every update check is authenticated by that certificate over mutual TLS — the same trust model used between machines that don't know each other yet but need to be certain who they're talking to.

If one installation's certificate is ever revoked, it affects exactly one machine. There is no shared secret to rotate fleet-wide.

One account, every device it protects

An account doesn't authenticate your traffic — your device's own certificate does that, on every single check. An account is the one place to see every install and pull a certificate the instant a machine goes missing.

Filtering runs the moment it's installed.

Create your account, then install. The service enrolls itself and starts inspecting traffic before the tray icon even finishes loading.
