Software you can trust on your own machine.

RealSec is a small security software company in Poland. We build precise tools for security teams, compliance officers and developers, and hold them to the standard we sell.

Precise
Each tool does one job and shows its working. When a number appears on screen, you can trace where it came from.
No telemetry
Our software does not report what you do. No usage analytics, no trackers, nothing sent home to improve the product. This site follows the same rule.
Yours to run
Where it can, the work happens on your machine or your own servers. Builds are signed, failure is designed in advance: NetWard fails open, so a bug of ours never takes your network down.

Products

Five instruments for two kinds of work. NetWard and snif are made for anyone with a Mac. RealSec, Iodynka and tinbe serve regulated organisations in Poland.

NetWard

Launching January 2027

See and decide every connection your Mac makes.

A per app firewall built on Apple’s Network Extension. Unknown connections stop and ask: allow or deny, for one host or the whole app, once or forever. Live connection map, terminal monitor, camera and mic watch. Signed, notarized, and it fails open on its own errors, so your network never breaks because of it.

snif

In development

See every request between the containers on your laptop.

A native sniffer for the stack running on your laptop. It captures HTTP/1.1, HTTP/2, gRPC, Redis and Postgres between containers, draws the topology with latency on every edge, and follows one request across services as a causal trace. Injecting latency and faults from the menu bar comes next.

RealSec

Live

GDPR, DORA, NIS2, AI Act and ISO 27001 in one engine.

Processes, systems, vendors and regulations kept as one model instead of a dozen spreadsheets. Signals reach the person who owns the problem, the risk engine and maturity reports run on the same data, and modules switch on with the licence. Also sold as documentation packs for ICT suppliers under DORA and NIS2.

Iodynka

Live in Poland

The working desk of a data protection officer.

Records of processing, DPIA, data subject requests and a map of where personal data lives, built on the RealSec engine and shaped for one job: running GDPR in a small or mid sized organisation. Available as a hosted service or a desktop installation.

tinbe

Early access

From regulation to evidence.

The working system of a compliance officer. New regulations are parsed into obligations, each obligation reaches the person who owns it through a signed magic link, and the evidence comes back into an audit trail kept as a hash chain. Conflicts of interest, gifts, a policy hub, whistleblowing and a board report run on the same engine.

Type
Compliance operations

Web, SaaS or on premises with a local LLM

About

RealSec is one founder, Błażej Lewartowski, and a short list of products worth putting a name on.

The company started with compliance software for the Polish regulated market, where RealSec, Iodynka and tinbe help organisations meet GDPR, DORA and NIS2 and run compliance day to day. The same habits now go into tools for everyone else: NetWard, a firewall for the Mac, and snif, which shows developers the traffic inside their local stack.

Small on purpose. Every product is designed, built and supported by the same person, so a question sent to hello@realsec.dev is read by someone who knows the code. Products ship when they pass testing, and the status next to each one says exactly where it stands.
