Which employers advertise the most cybersecurity jobs in Europe?

The headline

2,564 of 10,056 verified cybersecurity roles, about a quarter, sit with 57 organisations. The other three quarters are spread across roughly 3,400 employers advertising one, two or three roles each.

That shape matters more than the ranking. Cybersecurity hiring in Europe is not concentrated in a handful of giants. It is a long tail with a visible head, and the head is mostly intermediaries.

Why the split matters

Four different kinds of organisation appear on this list, and they buy completely different things. Reading it as one ranking of employers gets the commercial conclusion wrong.

An IT services firm advertising forty security roles is staffing client projects it has already won. A staffing agency advertising forty is speculatively filling a bench or advertising the same role in several places. A job board advertising forty is not an employer at all. Only the fourth group, in-house teams, is hiring people who will work on their own systems.

The tables below separate them.

IT services, consulting and integrators

These firms sell security capability to clients. They are the largest group on the list and the most multinational, which is why so many of them appear across four or five markets.

For anyone selling recruitment, contracting or training, this group is the most reliable buyer. Their hiring is tied to signed client work, so an open role represents committed revenue rather than a speculative headcount plan.

Staffing, recruitment and contracting

These organisations place people rather than employ them long term. ITOL Recruit at 199 roles is the largest single advertiser in the entire dataset.

Treat volumes in this group with care. A recruiter advertising the same role on several boards, or advertising a role it hopes to win rather than one it has been briefed on, inflates counts in a way an in-house employer does not.

They are still useful as a signal. A staffing firm running heavy security volume in a market is telling you that market has demand it cannot service, which is a selling opportunity for anyone with candidate supply.

Job boards and marketplaces

These entries are not employers. They appear because the platform itself is named as the advertiser on the listing.

Job-Room is the Swiss public employment portal, Direct Emploi and Capijobnew are French aggregators, Free-Work and Collective.work are freelance marketplaces, and Klient portalu Praca.pl is a placeholder used by anonymous advertisers on a Polish board.

They are excluded from any conclusion about employer demand, and any dataset that leaves them in is silently overstating the market.

In-house teams

Organisations building their own security function. This is the smallest group on the list, which is the most interesting finding on this page.

BWI GmbH is the German federal armed forces IT company and the largest genuine in-house advertiser. The Ministère des Armées and CEA make France unusual: defence and nuclear research recruit security staff directly rather than through integrators.

Two entries need a caveat. IU Internationale Hochschule and LearnWise are education providers hiring people to teach security rather than to practise it, and A&O Shearman is a law firm whose security roles sit in its own technology function.

What this tells you about selling into the sector

If you supply candidates, sell to the services firms first. They have committed client work, repeat demand and a procurement process that already handles suppliers.

If you sell security products, the in-house list is short and that is the point. The European market for security tooling is not the 3,400 companies advertising a role. It is the small number building teams big enough to run a platform.

If you sell to recruiters, the staffing group is your addressable market and it is crowded. Twenty agencies running twenty or more security roles each in seven countries is a small enough set to work by hand.

Ignore the boards. Any list you buy that contains Job-Room or Direct Emploi as employers was not cleaned.

How the index was built

Adverts were collected from public job sources across Germany, the United Kingdom, France, Poland, the Netherlands, Switzerland and Lithuania in August 2026. The raw security query set contains 18,149 adverts. 10,056 of those carry a job title that names a security function and only those are counted here.

Verification matches security terms in the title across the languages present: cyber, security, sécurité, Sicherheit, bezpieczeństwo, beveiliging, plus function names such as SOC, SIEM, DevSecOps, pentest, IAM, GRC, CISO and RSSI. It is a conservative test, so a genuine security role advertised under a generic engineering title is not counted.

Employer names were merged where the same organisation appeared under case or legal-form variants, so NTT America, NTT Data and NTT are counted once, as are Sii and Sii Sp. z o.o., Antal and Antal Sp. z o.o., and CGI and CGI Nederland. No other normalisation was applied, so some fragmentation remains.

This is a snapshot on one date, not a flow. Roles filled internally or through referral never appear.
