Stephen Breidenbach serves as Co-Chair of the firm’s Privacy, Cybersecurity & Technology Practice Group and concentrates his practice in technology related legal matters, including cybersecurity and privacy compliance.

Prior to beginning his career as an attorney, Mr. Breidenbach studied and practiced as a cybersecurity professional where he spent much of his time analyzing threats and reverse engineering malicious code.  His technical skillset includes computer forensics, networking, network security and computer programming.

Mr. Breidenbach has merged his technical background with his legal practice.  He works hand-in-hand with clients to help them better understand their use of technology and solve the complex legal problems which manifest when law and technology collide. These matters include helping companies meet their compliance obligations under the various cybersecurity, privacy and communications laws.  He assists companies in drafting written information security policies (WISPs), privacy policies, terms of use, structuring and reviewing data retention policies, drafting cybersecurity provisions for vendor agreements (such as Business Associate Agreements) and handling cybersecurity incidents (such as phishing attacks, denial of service attacks, etc.), including data breaches.  However, his technical background also affords him the vital knowledge necessary to handle a wide variety of other tasks in the electronic space.  As such, he is often involved in drafting software development contracts, advising on the Americans with Disabilities Act compliance for websites, reviewing rights issues related to the usage of open source code, handling online defamation (which includes negative reviews), drafting Software as a Service (SaaS) Agreements, handling Digital Millennium Copyright Act (DMCA) violations, determining compliance obligations for online advertising and protecting the intellectual property rights of clients’ electronic assets (such as software).

Mr. Breidenbach spends much of his free time developing software and interacting with the information technology and information security communities.  He is versed in such technologies as machine learning, chat bots, augment reality, altered reality, virtual reality and blockchain.  He has also assisted in the development of mobile apps and websites.
