Tines
Tines is a Dublin-founded enterprise software company building workflow automation for security, IT, and operations teams. The product became well known in cybersecurity because it gives frontline analysts a low-code way to automate repetitive response tasks without needing to maintain brittle custom scripts. Teams can connect alerts, ticketing tools, identity systems, cloud platforms, and communication apps into visual workflows that investigate incidents, enrich context, trigger approvals, and execute remediation steps automatically. That lowers manual workload while preserving auditability and human control over higher-risk actions. Over time, Tines has expanded beyond pure security orchestration into broader internal operations, making the platform useful anywhere a company needs reliable API-based workflow execution across multiple tools. Its traction reflects a larger shift in enterprise software toward operator-owned automation rather than centralized engineering bottlenecks. In the European ecosystem, Tines is also a strong example of an Irish infrastructure startup that scaled into a global category while staying connected to the region's talent and capital networks.

Tresorit
Tresorit is a Budapest-founded end-to-end encrypted cloud storage and file-collaboration company that positioned itself very early as the privacy-first European alternative to Dropbox and Google Drive for regulated industries: law firms, healthcare, financial services, and — notably — government and defense teams in Europe that cannot legally store sensitive files with US hyperscalers. Founded in 2011 by István Lám, Szilveszter Szebeni, and György Szilágyi, the product is built around zero-knowledge client-side encryption, so files are encrypted before they leave the user's device and Tresorit itself cannot read them even if compelled. The company famously ran a public one-million-dollar hacking challenge to demonstrate the robustness of its encryption, and has since been repeatedly cited by European regulators and data-protection authorities as a model for GDPR-aligned cloud collaboration. In 2021 Swiss Post acquired a majority stake in Tresorit as part of its digital sovereignty push — one of the most strategically significant Hungarian deep-tech exits.
