CyberLock Defense Insurance

Because AT&T business customers like you store large amounts of clients’ data, like home address, date of birth, credit card numbers and more, you are a prime target for cyber terrorists.

Lockton Affinity developed CyberLock Defense to protect your business from the associated costs of a cyber-attack and network breach. For as low as $425 annually, this affordable and comprehensive, standalone Cyber Liability policy provides you with:

Broad coverage

First and third party coverage options to address cyber extortion, breach of data privacy, contractual liability, copyright infringement and rogue employees.

No sublimits

The policy limit you select is the policy limit you get. If you select a $5M policy, you have full access to your $5M policy limit, even for incidents of cyber theft, social engineering loss, ransomware and more.

Flexible limits

Policy limit options range from $100,000 to $10M with premiums starting as low as $425.

Additional coverage

Business Interruption Expense and Extended Business Interruption coverage are included in your policy automatically, and at no extra cost.
