Pricing · clear numbers, no quoting games

Wire-level testing tool.
Free workbench. Paid tiers for the full stack.

Two paths: Engineering for shipping integrations, Security for breaking them.

We paywall power, not the basics. The AI assistant, OAuth2, GraphQL, collection import and git-native workspaces are free, forever — paid tiers add the heavy machinery. Switch anytime; nothing is deleted when you downgrade.

Per organisation

Don't see your protocol?

Missing a protocol you'd like in the mix?

No problem — and no plugin for you to write. Every protocol in VirtuProbe is hand-rolled against its RFC, and the module ecosystem is built to grow. A protocol we don't ship yet isn't a wall — it's something we can add for you. Tell us what you need and we'll wire it into the mix.

How licensing works

One license per user. Three devices each.

Every paid license is for one person, who can install and activate VirtuProbe on up to three of their own devices — laptop, desktop, a VM, whatever you work on. No floating seats, no per-device upsell.

Need to cover more people? Buy a license each. Enterprise is per organisation — unlimited users inside your domain, one invoice, one SSO config.

01One person. Buy a Security license — activate it on your laptop, your desktop, and a throwaway VM. Three devices, one you.
02A team. Five pentesters? Buy five licenses — each person gets their own, three devices apiece.
03Growing. Add licenses whenever you need them, prorated to your renewal anniversary.
04Whole org. Go Enterprise: unlimited users in your domain, self-hosted, one contract.

Frequently asked, honestly answered

Questions worth asking.

Can I switch between Engineering and Security tiers?

Yes, anytime. If you're already on Engineering and need fuzzing or the security protocols (SMB, Kerberos, SpamAssassin) for a specific engagement, upgrade to Security for that month and downgrade back. No commitment.

What's the difference between Engineering and Security?

Engineering is for building and testing your own integrations — APIs, email flows, LDAP-backed auth, cloud services — with the MITM proxy and service-virtualization mocks for debugging and standing in for unfinished services. Security adds the offensive kit: fuzzing, the security protocol suite (SMB, Kerberos, SpamAssassin) and the pentest libraries. Different jobs, different tools.

Do you offer free access for students or academics?

Yes. The VirtuProbe Academic License gives full Security tier access free, with verification (institutional .edu email, enrolment letter, or faculty page). Apply at /academic.

What happens if I downgrade?

Your data stays. Features above your new tier become read-only until you re-upgrade. Nothing is deleted.

Do you have GDPR / data residency options?

Yes — for Enterprise deployments, you self-host on your infrastructure in your jurisdiction. Contact sales for details.

Where does the binary run?

Free and Engineering: a desktop Electron app on your laptop. Engineering Pro and Security add a Docker server so the API runs inside your network. Enterprise is fully self-hostable on your own iron.

Do you take card or invoice?

Free / Engineering / Security: card via Paddle. Enterprise: invoice with PO, net-30 default, custom terms negotiable.

Can I export my probes if I cancel?

Yes. Probes and chains are local files in a documented format. Export from the app at any time — including after your license expires (Free tier permissions still apply).

Start with Free. Pick a path when you need it.

Most backend devs land on Engineering within a week. Most security folks land on Security within an hour. Most CISOs land on Enterprise after one procurement call.
