About Us
Look, we've been watching companies get hit hard. Ransomware. Data theft. The works. CoreSync started because we got tired of seeing businesses panic after the damage was done. We built something different — security that actually thinks like attackers do. Not some fancy software that sits there collecting dust. Real protection. Honest conversations about what your business actually needs (not what looks good on a PowerPoint). We're 18 people who genuinely care about keeping your data safe. That's it. That's what we do.
Over time, we’ve built a reputation for reliability, quality, and clear communication. We treat each project as a partnership and aim for outcomes that last.
Our Mission & Our Vision
Our Mission
Stop cyber threats before they reach your door. We combine aggressive threat hunting, real-time response, and no-nonsense guidance to keep your business breathing easy. No theater. No unnecessary complexity. Just effective security that works.
Our Vision
A world where small and medium businesses aren't sitting ducks for criminals. Where a breach isn't inevitable—it's exceptional. We're building the tools and culture to make that happen, one company at a time.
Our Core Values
The principles that guide everything we do
Radical Honesty
We tell you what's broken. Not what you want to hear. If your security's a mess, we say so. Then we fix it together.
Speed Over Perfection
Threats don't wait for committee meetings. We move fast. Deploy faster. Think smarter. Perfect is the enemy of secure.
Built for Real Business
Not theoretical security theater. We understand you've got budgets, legacy systems, and actual work to do. We work within reality.
Constant Adaptation
Attackers evolve every week. So do we. Our playbooks change monthly. Your protection never gets stale.
Our Story
CoreSync started in 2019 when our founder got fed up. Too many clients were losing everything because they couldn't afford the big enterprise security firms. So he built what he needed instead. The first 18 months were brutal—bootstrapped, working nights, learning what actually works in the wild. By 2021, we'd stopped our first major ransomware attack for a manufacturing plant in Cluj-Napoca. Word spread. Now we're protecting 47 companies across Romania and expanding into Hungary. Still lean. Still hungry.
