We Lock It Up

cbCrunch takes your security seriously. That's why we built cbCrunch with the same security technology used by online banks and financial markets. Then we added extra layers.

Powerful Security Features

256-bit TLS encryption
256-bit TLS encryption

While the current acceptable standard is 128-bit TLS (Transport Layer Security) encryption for sending and receiving sensitive information, cbCrunch enhances your data protection with 256-bit TLS encryption, treating your data as securely as your bank account.

images, files, and media content are securely stored on our custom encrypted content servers.


We place strict controls over our employees’ access to the data you and your users make available via the cbCrunch services, as more specifically defined in your agreement with cbCrunch covering the use of the cbCrunch services ("Customer Data"), and are committed to ensuring that Customer Data is not seen by anyone who should not have access to it.

The operation of the cbCrunch services requires that some employees have access to the systems which store and process Customer Data. For example, in order to diagnose a problem you are having with the cbCrunch services, we may need to access your Customer Data.
These employees are prohibited from using these permissions to view Customer Data unless it is necessary to do so. We have technical controls and audit policies in place to ensure that any access to Customer Data is logged. All of our employees and contract personnel are bound to our policies regarding Customer Data and we treat these issues as matters of the highest importance within our company.

Personnel Practices

cbCrunch conducts background checks on all employees before employment, and employees receive privacy and security training during onboarding as well as on an ongoing basis. All employees are required to read and sign our comprehensive information security policy covering the security, availability, and confidentiality of the cbCrunch services.

Security Features for Team Members and Administrators

In addition to the work we do at the infrastructure level, we provide Team Administrators of paid versions of the cbCrunch services with additional tools to enable their own users to protect their Customer Data.

  • Access Logging : Detailed access logs are available both to users and administrators of paid teams. We log every time an account signs in, noting the type of device used and the IP address of the connection. Team Administrators and owners of paid teams can review consolidated access logs for their whole team. We also make it easy for administrators to remotely terminate all connections and sign out all devices authenticated to the Slack services at any time, on-demand.
  • Team-Wide Two-Factor Authentication :
  • Access Logging : Team Administrators can require all users to set up two-factor authentication on their accounts. Instructions for doing this are available on our Help Center.
  • Single Sign On : Administrators of paid teams can integrate their cbCrunch services instance with a variety of single-sign-on providers. Teams on the ‘Standard’ plan can enable Google Apps for Domains as their authentication provider, and teams on the ‘Plus’ plan can enable SAML SSO with providers such as OneLogin, Okta, Centrify, and Ping Identity.
  • Data Retention : Owners of paid cbCrunch teams can configure custom message retention policies on a team-wide and per-channel basis. Setting a custom duration for retention means that messages or files older than the duration you set will be deleted on a nightly basis.
  • Deletion of Customer Data : cbCrunch provides the option for workspace Primary Owners to delete Customer Data at any time during a subscription term. Within 24 hours of workspace Primary Owner initiated deletion, cbCrunch hard deletes all information from currently-running production systems (excluding team and channel names, and search terms embedded in URLs in web server access logs). cbCrunch services backups are destroyed within 14 days.
  • Return of Customer Data : Information about the export capabilities of the cbCrunch services can be found at our Help Center.

Data Encryption in Transit and At Rest

The cbCrunch services support the latest recommended secure cipher suites and protocols to encrypt all traffic in transit. Customer Data is encrypted at rest. We monitor the changing cryptographic landscape closely and work promptly to upgrade the service to respond to new cryptographic weaknesses as they are discovered and implement best practices as they evolve. For encryption in transit, we do this while also balancing the need for compatibility for older clients.


We understand that you rely on the cbCrunch services to work. We're committed to making cbCrunch a highly-available service that you can count on. Our infrastructure runs on systems that are fault tolerant, for failures of individual servers or even entire data centers. Our operations team tests disaster-recovery measures regularly and staffs an around-the-clock on-call team to quickly resolve unexpected incidents.

Disaster Recovery

Customer Data is stored redundantly at multiple locations in our hosting provider’s data centers to ensure availability. We have well-tested backup and restoration procedures, which allow recovery from a major disaster. Customer Data and our source code are automatically backed up nightly. The Operations team is alerted in case of a failure with this system. Backups are fully tested at least every 90 days to confirm that our processes and tools work as expected.

Network Protection

In addition to sophisticated system monitoring and logging, we have implemented two-factor authentication for all server access across our production environment. Firewalls are configured according to industry best practices and unnecessary ports are blocked by configuration with Cloud Security Groups.

Host Management

We perform automated vulnerability scans on our production hosts and remediate any findings that present a risk to our environment. We enforce screens lockouts and the usage of full disk encryption for company laptops.


cbCrunch maintains an extensive, centralized logging environment in its production environment which contains information pertaining to security, monitoring, availability, access, and other metrics about the cbCrunch services. These logs are analyzed for security events via automated monitoring software, overseen by the security team.

Incident Management And Response

In the event of a security breach, cbCrunch will promptly notify you of any unauthorized access to your Customer Data. cbCrunch has incident management policies and procedures in place to handle such an event.

External Security Audits

We contract with respected external security firms who perform regular audits of the cbCrunch services to verify that our security practices are sound and to monitor the cbCrunch services for new vulnerabilities discovered by the security research community. In addition to periodic and targeted audits of the cbCrunch services and features, we also employ the use of continuous hybrid automated scanning of our web platform.

Product Security Practices

New features, functionality, and design changes go through a security review process facilitated by the security team. In addition, our code is audited with automated static analysis software, tested, and manually peer-reviewed prior to being deployed to production. The security team works closely with development teams to resolve any additional security concerns that may arise during development. cbCrunch also operates a security bug bounty program. Security researchers around the world continuously test the security of the cbCrunch services, and report issues via the program. More details of this program are available at the bounty site.
