As a company that takes data security and privacy very seriously, we recognize that Mailchimp’s information security practices are important to you. While we don’t like to expose too much detail around our practices (as it can empower the very people we are protecting ourselves against), we have provided some general information below to give you confidence in how we secure the data entrusted to us.
Data Center Security
- Mailchimp delivers billions of emails a month for millions of users. We use multiple MTAs, placed in different world-class data centers around the United States.
- Our data centers manage physical security 24/7 with biometric scanners and the usual high tech stuff that data centers always brag about.
- We have DDOS mitigation in place at all of our data centers.
- We have a documented "in case of nuclear attack on a data center" infrastructure continuity plan.
Protection from Data Loss, Corruption
- All databases are kept separate and dedicated to preventing corruption and overlap. We have multiple layers of logic that segregate user accounts from each other.
- Account data is mirrored and regularly backed up off site.
Application Level Security
- Mailchimp account passwords are hashed. Our own staff can't even view them. If you lose your password, it can't be retrieved—it must be reset.
- All login pages (from our website and mobile website) pass data via TLS.
- The entire Mailchimp application is encrypted with TLS.
- Login pages and logins via the Mailchimp API have brute force protection.
- We perform regular external security penetration tests throughout the year using different vendors. The tests involve high-level server penetration tests, in-depth testing for vulnerabilities inside the application, and social engineering drills.
Internal IT Security
- Mailchimp offices are secured by keycard access and biometrics, and they are monitored with infrared cameras throughout.
- Our office network is heavily segmented and centrally monitored.
- We have a dedicated internal security team that constantly monitors our environment for vulnerabilities. They perform penetration testing and social engineering exercises on our environment and our employees. Our security team includes OSCP and CISSP certified members.
Internal Protocol and Education
- We continuously train employees on best security practices, including how to identify social engineering, phishing scams, and hackers.
- Employees on teams that have access to customer data (such as tech support and our engineers) undergo criminal history and credit background checks prior to employment.
- All employees sign a Privacy Safeguard Agreement outlining their responsibility in protecting customer data.
- In order to protect our company from a variety of different losses, Mailchimp has established a comprehensive insurance program. Coverage includes, but is not exclusive to: coverage for cyber incidents, data privacy incidents (including regulatory expenses), general error and omission liability coverage, excess cyber liability coverage, property and business interruption coverage, as well as international commercial general liability coverage.
