You Are Not "Too Small" to Be a Target
Many local business owners think hackers only target large corporations like Target or Equifax. Small businesses are targeted all the time, because they have valuable data (customer info, credit cards, employee records) but rarely have enterprise-level security.
Massachusetts Data Privacy Laws
Massachusetts has some of the strictest data privacy laws in the country (201 CMR 17.00). If you collect personal information from residents, you are legally required to have a Written Information Security Program (WISP).
Failure to comply can result in massive fines if a breach occurs.
4 Essential Security Layers
1. Multi-Factor Authentication (MFA)
Passwords are no longer enough. Require MFA for every critical system, especially email and CRM.
2. Endpoint Protection
Basic antivirus is not enough. You need modern Endpoint Detection and Response (EDR) that monitors behavior, not just known viruses.
3. Automated Cloud Backups
If you get hit by ransomware, your only defense is a clean, disconnected backup. Backups must be automated, encrypted, and tested regularly.
4. Employee Training
The weakest link in any security system is human error. Train your team to recognize phishing emails and suspicious links.
Contact our team for a security audit, or take the Cyber Risk Quiz to see how exposed you are.
Frequently asked questions
Does my Massachusetts small business need a WISP?

What are the Massachusetts small business cybersecurity requirements?
If you collect personal information about Massachusetts residents, 201 CMR 17.00 requires a Written Information Security Program. Back it with MFA, endpoint protection, tested backups and staff training, and confirm your obligations with your attorney.
What is 201 CMR 17.00?
It is the Massachusetts data privacy regulation that requires businesses holding residents' personal information to keep a Written Information Security Program (WISP). It is among the strictest state rules in the country.
What happens if a Massachusetts business doesn't have a WISP?

Why do hackers target small businesses in Massachusetts?
Small businesses hold valuable data like customer info, card numbers and employee records, but rarely have enterprise-level security.
Which systems should have multi-factor authentication first?
Email and your CRM, then every other critical system. Passwords alone are no longer enough.
How often should a small business test its backups?
Regularly. Backups should be automated, encrypted and kept disconnected, and you should practice restoring them so you know they work before ransomware strikes.
