  • The team delivers work of consistently excellent technical quality on highly complex data protection matters. Their understanding of the GDPR framework and the nuanced regulatory positions we operate under is deep. What sets them apart is the balance they strike between pace and prudence — they progress matters independently and at the speed we need. They are proactive in the truest sense: they identify risks likely to attract regulatory scrutiny and come to us with options and solutions, not just concerns. They routinely check precedents, prior regulatory communications, and existing previous advice to ensure our positions remain coherent and defensible. The team has made key contributions on some of our most critical and scrutinised workstreams, including the launch of relevant tools and complex engagements with the Irish Data Protection Commission. Beyond the technical excellence, they are a genuine pleasure to work with — collaborative, dedicated, and intellectually curious. They are trusted external partners in every sense.
  • What truly distinguishes this team is their proactive approach to legal counsel. Rather than simply reacting to issues as they arise, they consistently anticipate potential risks and regulatory developments, flagging them early and presenting well-considered options before matters escalate. This forward-looking mindset means we are never caught off-guard and can plan strategically rather than firefight. The team's attention to detail is exceptional. They have a meticulous approach to reviewing complex documentation, identifying nuances and interdependencies. This granular precision gives us a high degree of confidence in the accuracy and completeness of their work product, which is essential given the complexity and fast-evolving nature of European/UK data regulation. Their technical depth also sets them apart. They do not deal in generalities — their advice is grounded in a sophisticated understanding of the underlying technology, data flows, and product architecture. This means their legal analysis is practical and operationally relevant, not abstract. They are able to engage meaningfully with engineering and product teams, bridging the gap between legal requirements and technical implementation in a way that few law firms can match. Compared to other firms, this combination of proactivity, precision, and technical fluency is rare. Many practices may offer one of these qualities, but the integration of all three provides a level of service that consistently exceeds expectations and enables faster, more confident decision-making.
  • Fiona Ghosh is exceptional. Fiona's knowledge of AI, particularly in the context of financial services, is incredibly impressive. She consistently provides clear, pragmatic, and commercially focused advice that has supported both governance design and the delivery of key initiatives within our business. Her ability to translate complex regulatory developments into actionable guidance is second to none. I'd recommend Fiona to anyone.
  • Excellent knowledge, incredibly approachable and transparent. I feel like I'm working alongside Ashurst Perkins Coie as part of a team.
