Areas of Practice

PRIVILEGE Protection Plan

If your company suffers a breach your assessment results may have to be turned over to anyone that has a claim against you. If performed under the advice of counsel, all assessment results are protected by attorney-client privilege! For a nominal annual fee, your company can protect its assessment results. Most importantly, the results can’t be used against you!

Regulatory and Framework Assistance

Demystifying what it means to be "compliant" and "reasonable." We help our clients create a proactive cyber security program using the appropriate framework that is relevant for their business.

Cyber contract negotiations

Many companies go into contract negotiations and sign contracts not knowing what their requirements are to protect sensitive data. With our guidance, our clients not only better understand their cyber security and privacy requirements, they know how to best protect the sensitive data entrusted to them.


Small and mid-sized companies often struggle with many aspects of cyber security and privacy. What they need is legal advice from attorneys who are deeply entrenched in the particularities of cyber security and privacy law. We can help.

Incident Response & Investigation

No company wants to deal with a breach! But having trusted counsel that understands both the legal and technological aspects of a breach, gives our clients an added sense of security that they are well advised and prepared.
