Ash Costello, Head of Ziliak Law’s Data Privacy Practice, advises on data privacy, financial services and blockchain/crypto matters.
Ash regularly counsels clients on data privacy developments particularly CCPA, GDPR, and GDPR (UK). This includes privacy risk management and mitigation, compliance, product counselling, preparing policies and procedures, information governance, preparing and managing responses to user requests and regulatory inquiries, breach preparation and response, and international data transfers. Her experience navigating complex and conflicting regulatory requirements when she acted as Head of Legal for one of the top fund administrators, allows her to understand client objectives and provide commercially pragmatic solutions to her clients.
Ash’s clients span diverse industries including financial services, retail, security, pharmaceutical and medical entities. Her ‘privacy in blockchain’ clients include ZKP/SMPC developers, crypto-blockchain platforms and DAOs, as well as entities wishing to exploit these disruptive technologies.
Working in Private Practice in London, Ash advised on financial services laws particularly relating to investment funds. She formerly worked inhouse as Head of Legal for one of the largest fund administrators and custodians worldwide.
Ash was appointed a member of the Expert Panel of the European Blockchain Observatory and Forum (EUBOF), a body formed by the European Parliament and now under the aegis of the European Commission (the governing bodies of the European Union). She regularly contributes to their workshops and publications including on matters such as NFTs (non-fungible tokens), DAOs (decentralized autonomous organizations) and Smart Contracts. She is the Co-Chair of the Privacy Working Group of the International Association of Trusted Blockchain Applications (INATBA) where she explores developments regarding privacy in and for blockchain including (among others) ZKPs (zero knowledge proofs), and SMPC (secure multi party computations).
