For founders, managing directors and entrepreneurs. Ideal just before or already in the phase of 1 to 15 million EUR in revenue.

This is exactly where many reach the point where the old way of working no longer holds — but the new one isn't within reach yet.

This sparring isn't for you if you're looking for someone to tell you what you want to hear. It's for you if you're ready to take honest feedback and act on it — even when it's uncomfortable.

It starts with a free first conversation. After that, the rate is 300 EUR per hour, billed in 15-minute increments. You only pay for what you actually use. No retainers, no minimum term.

For entrepreneurs with a bigger development need, there are also intensive formats with a workshop, regular calls and work with the leadership team. You'll discuss that in the first conversation.

Jona has built a company himself — scaled it, steered it through crises and restructured it. He has made leadership mistakes, lost employees, burned money, prioritised wrong and learned from it. He doesn't sell theory, but experience from entrepreneurial reality.

No certificate replaces that.

Go to IT Security and use the request form (with a phone number for a direct call back). Requests through it are handled as a priority and forwarded straight to Jona. Sometimes hours make the difference — that's why this direct route exists.

Too many people involved, too little clarity. You're in the middle, carrying the responsibility.

Jona is your external companion at management level. He oversees your IT providers and incident responders, translates between their technical language and your business reality, and makes sure recovery follows your business priorities, not technical logic.

Insurers, authorities, data protection, leadership team — Jona makes sure you know what you say and what you decide.

Because these are two completely different roles.

An incident manager, a forensics team or a SOC works on the incident: isolating systems, locking out attackers, preserving evidence, recovering. That's indispensable — and exactly right.

Jona works on the decisions. Do we pay? When do we inform customers, authorities, the press? What do we tell the board? Do we shut down production? Who can we still trust? These questions don't land with the provider — they land with you. And you make them under time pressure, with incomplete information, while everyone is looking at you.

His role: at your side, not at the system. He translates between tech and management, lays out the options with their consequences, and tells you honestly what he would do in your place — and what he wouldn't. From more than 100 incidents he has handled, he knows how these situations play out.

In short: your IR provider resolves the incident. Jona makes sure you make the right decisions along the way.

Jona is founder and CEO of suresecure GmbH, one of the leading providers of Security Operations Centers and incident management in Germany. On top of that, he founded securance GmbH, a specialised broker for cyber insurance.

Over more than ten years, he has handled more than 100 IT security incidents in a wide range of roles. From mid-sized businesses to corporations, from ransomware to data breaches.

What he brings: deep technical knowledge and the ability to translate it into the decisions you have to make as a managing director.

For any entrepreneur or decision-maker caught in an IT security incident who feels: everyone's talking, no one speaks my language. The techies are doing something, but I don't know what. I have to make decisions, but I have no basis for them.

If that's how you feel right now — then you're in exactly the right place.

Through the Speaker page and the request form there. Jona gives keynotes on cybersecurity, entrepreneurship and leadership — also as a combination. He's available for podcasts and panel discussions too. And he'll tell you honestly whether he's a fit for your format.
