Data-Security & Privacy

As a company that takes data security and privacy very seriously, we recognize that INBOX’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

  • INBOX delivers billions of emails a month for millions of users. We use multiple MTAs, placed in different world-class data centers around the Canada.
  • 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

  • INBOX 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 INBOX application is encrypted with TLS.
  • Login pages and logins via the INBOX API have brute force protection.

Internal IT Security

  • Our office network is heavily segmented and centrally monitored.
  • Our INBOX employees are able to access the management account with VPN.
  • INBOX employees to access INBOX user data, our INBOX user must grant access to our employee.
  • 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, INBOX 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.

ISO 27001 Certification

The International Organization for Standardization 27001 Standard (ISO 27001) is an information security standard that ensures office sites, development centers, support centers, and data centers are securely managed. These certifications run for 3 years (renewal audits) and have annual touchpoint audits (surveillance audits).

Protecting Ourselves Against You

Yes, you heard that correctly. We can secure ourselves like Fort Knox, but if your computer gets compromised and someone gets into your INBOX account, that’s not good for either of us.

  • We monitor and will automatically suspend accounts for signs of irregular or suspicious login activity.
  • Certain changes to your account, such as to your password, will trigger email notifications to the account owner.
  • We monitor accounts and campaign activity for signs of abuse.
  • In addition to our scalable algorithms, we employ another layer of human reviewers, who monitor for anomalous account and email activity.
  • We provide the ability to establish tiered-levels of access within accounts.

Investing in Your Privacy

  • Our Legal team partners with our developers and engineers to make sure our products and features comply with applicable international spam and privacy laws.
  • We retain a law firm in the UK to consult on EU privacy issues.
  • We undergo annual verification with a U.S. based third party-outside compliance reviewer under the Privacy Shield verification program, and we have certified our compliance with the EU-U.S./Swiss-U.S. Privacy Shield Frameworks.
  • We are members of the ANA, ESPC, OTA, and MAAWG.
  • Our corporate attorneys and Legal Compliance Manager are active members of the International Association of Privacy Professionals (IAPP) and collectively hold the certifications of CIPP/US, CIPP/G, and CIPP/E.

  • Provide a clear, concise description of the steps needed to reproduce any vulnerability you submit.
  • Provide the complete details related to the security issue, including proof-of-concept (POC) URL, as well as the details of the system(s) where tests have been conducted.
