‘The team is made up of both legal and non-legal professionals who are tops in their respective fields. Whether the issue is security, privacy, email, lobbying, advertising, breaches, or even new and emerging areas such as genomics or automated vehicles, Venable has invested in talent that is world-class and yet accessible to their clients.’

‘I’ve worked extensively with Michael Signorelli, partner, who excels at making sure that his clients receive practical and business-impacting advice in all manners of areas which are important to my organization. These range from regulatory guidance, legal compliance, lobbying strategy, technical advice and even business advice. In my experience, Mike’s clients have ready access to him – making them that much better prepared to succeed.’

‘I know it sounds cliched, but Venable’s Cyber law practice acts as a true partner in dealing with me and my company. Most firms give lip service to this notion, but Venable genuinely puts it into practice. They not only strive to provide cost-effective and practical guidance to my client, but they also also try to make me look good in the process!’

‘Aside from the fact that Milo Civadanes is an extremely smart, talented, practical, organized and cost-effective attorney who knows his subject-matter like no one else, the three attributes that stand out to me are: (1) He is a genuine person who I have a personal connection with and trust and who breathes the same values that I and my company try to follow; (2) Milo has such a breadth and wealth of experience (especially in the policy-making arena) that I can rely on Milo not only for the black letter legal advice but also for a deep understanding of how to tackle legal questions for which there is no clear answer or precedent, which is often the case in this field; and (3) Milo really understands how to communicate with in-house counsel and senior management – he is the master of taking a complex legal issue that could go in a thousands different directions and summarizing it into a one page memo.’

‘Venable has served as our outside counsel for privacy and data security matters for at least 7 years. They have deep experience and knowledge in the advertising space as well as active involvement in privacy legislative discussions/activities at the federal and state level. They also have significant experience in helping companies navigate exchanges with government regulators and investigators. These capabilities and strengths have made them invaluable both in the context of addressing risks to the Company as well as for long term planning as it relates to our privacy practices.’

‘Mike Signorelli acts as our primary outside counsel for privacy matters. He has provided invaluable advice and support for all our privacy processes and strategy. He also does an excellent job of being involved in and keeping us up to speed on the rapidly developing/changing regulatory landscape so that we are not in a position of reacting to developments but instead we are prepared for them. He also gives thoughtful business focused advice taking into account the competing needs of our business and is excellent at helping us navigate the legal and PR risks associated with the business.’

Julia Kernochan Tama was our lead counsel in addressing and responding to a government investigation. Julia is extremely knowledgeable and thoughtful in her advice and representation. She displays a level headedness, confidence and experience level that provided a lot of comfort to us during what was a very significant legal matter facing our Company. We felt that we were certainly benefiting from her experience in similar matters. She deftly handles surprises and is thoughtful and creative in addressing problems. She was also appropriately communicative and willing to marshal firm resources to support us throughout our responses, even when many of our internal resources were needed for other activities.’

‘The team is incredibly responsive and knowledgeable in their respective areas of expertise. They have provided invaluable guidance when navigating particularly complicated areas of law. Specifically, Kelly DeMarchis Bastide has been a great partner for our organization.’

The privacy and security team collaborates seamlessly across the globe when advising clients. The firm is dedicated to hiring experienced lawyers that can parachute in, establish client rapport and trust and develop a multifaceted workflow to tackle any client challenge.

Brenda Sharton is an amazing senior lawyer who combines deep experience and knowledge with a calm and collected approach.

Brenda Sharton was my primary contact and she is an industry leader in this area. She was not only knowledgeable on the legal issues in our case, but gave practical advice as well on avoiding issues in the future. We have a unique business model where our litigation team will draft some of the memorandums and briefing. Many firms do not like to work this way. Brenda was a great partner and was respectful of what my team brought to the table. She was able to work with our team in a way that lent value to the process and kept our costs to a reasonable level.

Brenda Sharton is a brilliant lawyer and a great client advocate. She is the lawyer you want in your corner. As a seasoned litigator and an experienced data security lawyer, she manages crises with confidence, finesse and strategy. Brenda will get into the weeds with the technical team and in the same breath turn to the legal team to interpret the significance and how it aligns with the bigger picture. Few lawyers have her depth, acumen and empathy but none have the same level of sincerity.

Brenda was able to work with my team on an alternative fee arrangement. As noted above, my team does hands on litigation work so we were able to take the budget proposed by Brenda and decide if we could do part of the work to bring costs to what we felt was manageable. Brenda was great at working with us on this and made us feel like we were part of a team. It was a very enjoyable experience and we got a fantastic result due in large part to Brenda’s leadership and partnership.

Brenda Sharton is one of the most experienced privacy lawyers in the market today, with deep experience and the ability to translate complexity in a way that is actionable and understandable. She cuts through the noise and focuses everyone on what is critical.

Karen Neuman is very responsive and provides very pragmatic advice.

Alysa is also fantastic about providing realistic budgets for projects and managing to those budgets. Finally, Alysa does an outstanding job bringing in other experts from her firm. As a result, a relationship that began with the scope limited to data breach preparation has expanded to include privacy counselling, insurance review, government contact counselling, and litigation support.’

She is easy to run “quick” issues by and a true partner, looking to provide value add where she can. She also has many connections in our industry and has enabled peer connections, which is always helpful. She truly embodies the term “trusted advisor” in all regards.’

Lauren Myers – while Lauren is an associate, she works on several matters for us and I think she is excellent. She provides thoughtful, sound advice and her written work is excellent. She is also incredibly responsive.’

‘My primary contact point has been Alysa Hutnik and she is great. Fantastic client service, but not sycophantic or meek. She’ll give you real advice. She doesn’t respond with lots of initial or follow-up questions–I love that. I’m not coming to you to have to answer more questions–I’m coming to you for answers!

He, too, gives good practical advice and doesn’t over lawyer.

Kim Peretti, David Keating, and Maki DePalo are amazing to work with. They are flexible, accommodating, innovative, and apply a business mindset with their advice, which can be hard to find. They don’t “over lawyer”, but instead provide meaningful, practical advice in record time. They are might right hand and I am grateful for them!
