Security clearance (Ü1–Ü3): what companies and candidates really need to know
Security clearance is seen as the biggest obstacle to getting into the defence sector. Rightly so - but it is also used as an excuse. Both are true.
Demand for qualified staff in the security and defence industry is higher than it has ever been. And the need for state security clearances has hit an all-time high at the same time. Secunet CEO Marc Julian Siewert summed it up to the Handelsblatt: "Demand for security-cleared people is shooting up enormously."
At the same time, security clearance regularly leads to false assumptions on both sides of the recruiting process - among candidates who underestimate it, and among companies that treat it as an insurmountable obstacle. Both are wrong.
What security clearance actually means
In Germany there are three levels of security clearance, governed by the German Security Clearance Act (SÜG) and, for private companies, the responsibility of the German Federal Ministry for Economic Affairs (BMWE):
The "Ü1" is the basic level and usually takes four to eight weeks. It examines previous convictions, ongoing proceedings, CV and financial circumstances.
The "Ü2" level is an extended check running three to six months. On top of that, social networks are evaluated, spouses and partners are included, and in some cases people from the professional and private environment are interviewed.
The "Ü3" is the most extensive level of checking and takes six to nine months - in some cases, particularly after longer stays in security-critical countries such as Russia or China, up to 18 months.
These checks are not bureaucracy for its own sake. Germany is regarded as a prime target for Russian and Chinese intelligence services. The growth of the defence industry opens up potential gateways for espionage and sabotage. Security clearance is therefore a necessary process - even if parts of it should be reformed and given more capacity.
The real problem: not the clearance itself, but how it is handled
For many companies, especially those newly entering the defence sector, security clearance becomes a brake on growth. Hires are delayed, project start phases are stretched out, and candidates who were firmly planned in cannot be deployed operationally for months.
Yet the decisive question is not whether the clearance happens - that is not negotiable. The decisive question is how companies use the waiting time.
The smartest players in the market actively use what is known as the pre-clearance phase. Instead of six months of idle time, a structured integration phase takes shape: training, tool onboarding, process understanding, simulations, project involvement without classified access. Plan that well and, at the end of the waiting time, you have an employee who has arrived in the company emotionally and professionally - and who can go operational the moment clearance is granted. That is a real competitive advantage in recruiting: candidates can be won over for a model that offers them a meaningful entry phase despite the wait.
What candidates specifically need to know
For applicants, the first thing to say is this: security clearance is very rarely an absolute disqualifying factor. Many interesting profiles come from elsewhere in the EU or have international CVs - that complicates the process, but it does not make it impossible.
Relevant factors are longer stays in countries such as Russia or China, existing financial obligations, or connections to people in security-critical positions. Anyone who reflects honestly on their own CV can work out early which level of clearance might apply to them - and whether there are factors that will draw the process out.
Important: the application process and the security clearance can run in parallel. There is no reason to start looking only once clearance has been granted. Quite the opposite: starting early buys you a head start.
Where reform is needed
The current situation is unsatisfactory for everyone involved. The BMWE's capacity is not built for the massive increase in clearance requests. Politicians are holding out the prospect of simplifications - but concrete, fast-acting solutions are not yet in sight.
One approach under discussion is voluntary advance security clearance: people who are interested in a career in the defence sector in principle could go through the check proactively - before they even apply for a specific role. That would allow companies to draw on candidates who have already been checked and to speed up ramp-up phases considerably. Implementation would require a significant increase in staff at the vetting authority - combined with rule-based process streamlining and the targeted use of legally sound AI support.
Conclusion: no showstopper - but a subject to be taken seriously
Security clearance is no reason to turn down an excellent candidate. It is also no reason for an applicant to bury their head in the sand. It is a structural reality of this industry - one you have to know, take seriously and actively manage.
Companies that understand this and shape their pre-clearance phase strategically have a clear advantage. So do candidates who communicate transparently and get the process moving early. What remains is the call to politicians: reform and capacity building are overdue. The security and defence industry's need for skilled people will not wait.
