Dublin is often referred to as the data capital of Europe, hosting hyperscale data centres that power much of the continent’s digital economy. But where there is data, there is risk. In response, the city has spawned a sophisticated cybersecurity ecosystem that goes far beyond basic antivirus software.
Dublin’s founders are building the plumbing of modern security with autonomous automation platforms, next-generation encryption standards, and compliance engines that navigate the complex landscape of GDPR. These companies are engineering the defences for a world where the perimeter has dissolved, and identity is the only firewall.
Here are the 10 cybersecurity startups in Dublin you need to know in 2026.
Tines
Eoin Hinchy and Thomas Kinsella founded Tines to address the overwhelming volume of repetitive alerts that can burn out security analysts. The company has raised over $146 million from investors such as Felicis and Accel to develop a no-code automation platform. Tines enables security teams to drag-and-drop actions into workflows that automatically handle phishing attacks, suspicious logins, and patch management, all without requiring a single line of Python. By acting as the connective tissue between disparate security tools, Tines transforms security operations from a reactive fire-fighting exercise into a streamlined engineering discipline.
Evervault
Shane Curran founded Evervault with a radical premise, developers should never actually touch sensitive data. Backed by Sequoia Capital and Index Ventures with over $20 million in funding, Evervault builds encryption infrastructure that allows companies to process data without ever decrypting it in their own databases. Their encryption as code platform integrates with just a few lines of code, ensuring that credit card numbers and health records remain encrypted at rest, in transit, and throughout processing. This effectively creates a zero-trust environment where a data breach yields only useless, scrambled text.
Vaultree
While traditional encryption protects data when it is stored, Vaultree protects data while it is being used. Founders Ryan Lasmaili, Tilo Weigandt, and Shaun McBrearty developed a breakthrough in Fully Homomorphic Encryption (FHE) that allows organisations to query and compute encrypted data at near-plaintext speed. Following a $12.8 million Series A led by Molten Ventures, they are solving the last-mile problem of encryption for financial institutions and healthcare providers. Their technology ensures that even if a server is compromised while a query is in progress, the data remains mathematically secure.
ID-Pal
Colum Lyons founded ID-Pal to fix the friction of Know Your Customer (KYC) compliance. The company offers a SaaS platform that enables businesses to verify a customer’s identity in seconds through biometrics and document analysis. Having raised €7 million to expand into the US and UK, ID-Pal employs a multi-layered verification approach that verifies document integrity against a global database and utilises liveness detection to prevent spoofing. Their solution is used by over 30 industries, ranging from grant agencies to stockbrokers, to avoid identity fraud without compromising the user onboarding experience.
Edgescan
Eoin Keary and Rahim Jina built Edgescan to move vulnerability management beyond the annual audit model. Their platform provides continuous, full-stack vulnerability assessment that covers everything from web applications to cloud infrastructure. Acquired by private equity for a significant sum to drive global expansion, Edgescan combines automated scanning with human validation to ensure that reported vulnerabilities are real and actionable. They provide the risk intelligence that allows CISOs to prioritise which patches to apply first based on actual exposure rather than theoretical severity.
Nova Leah
Dr Anita Finnegan founded Nova Leah to address the terrifying reality of hacked pacemakers and insulin pumps. Spinning out of academic research, the company provides a cybersecurity risk management platform specifically for connected medical devices. Their SelectEvidence software automates the complex regulatory compliance required by the FDA and EU MDR, tracing potential vulnerabilities through the entire supply chain of a medical device. By ensuring that security is baked into the design phase of medical hardware, Nova Leah protects patient safety in an increasingly connected healthcare environment.
Corrata
Colm Healy founded Corrata to protect the most vulnerable endpoint in the modern enterprise: the smartphone. As mobile phishing (smishing) attacks rise, Corrata provides a mobile immune system that detects and blocks malicious attacks on iOS and Android devices without inspecting private user content. Their technology operates directly on the device rather than tunnelling traffic to a cloud proxy, which preserves user privacy and battery life while blocking connections to phishing sites and command-and-control servers. This makes them a critical partner for organisations with large mobile workforces.
Getvisibility
Ronan Murphy and Paul Lowry created Getvisibility to solve the problem of unstructured data sprawl. Using advanced machine learning, their platform scans an organisation’s entire network to find, classify, and secure sensitive documents that are often hidden in legacy file servers or cloud folders. Having raised €10 million in Series A funding, Getvisibility acts as the foundational layer for data governance. It ensures that, before a company deploys an AI model, it knows exactly where its intellectual property and PII reside, thereby preventing accidental data leaks during digital transformation projects.
VigTrust
Mathieu Gorge founded VigTrust to tackle the complex web of third-party risk. In a hyper-connected economy, a company is only as secure as its weakest vendor. VigTrust provides a Vendor Risk Management (VRM) platform that automates the assessment and continuous monitoring of third-party security postures. Their 5 Pillars of Security framework helps organisations educate and validate their supply chain, moving beyond simple questionnaires to a dynamic view of vendor risk. This is essential for compliance with regulations such as DORA and NIS2, which hold companies accountable for the security of their supply chains.
Dataships
Ryan McErlane and Michael Storan founded Dataships to make data privacy a growth engine rather than a compliance burden. Their platform automates the complex web of GDPR and CCPA compliance, handling cookie consents, data access requests, and privacy policies in a dynamic manner. Backed by extensive seed funding, Dataships focuses on building trust with consumers by making privacy transparency a visible part of the customer journey. Their tools help companies navigate the complex landscape of global privacy laws without requiring a dedicated legal team for every new market they enter.
