Security & Compliance

Security Overview

At Fennel, safeguarding customer data is at the heart of our mission. It is imperative to cultivate a security-centric culture in order to gain the confidence of organizations addressing significant challenges. As a result, we infuse security best practices throughout all facets of our operations and product development, persistently striving to enhance our security measures.

Here is a non-exhaustive list of security best practices followed by our team:

Culture of Security

Security Program

Fennel is committed to a security program ensuring the confidentiality, integrity, and availability of customer data. Our information security policies, revised at least annually, are designed to implement best practices in areas such as access control, risk management, change management, incident response, and other vital aspects. These policies are based on established industry frameworks, and our controls have been rigorously certified through a SOC-2 Type 1 assessment. Feel free to reach out to [email protected] to request a copy of our certified report.

Our People

The foundation of Fennel's security program rests on its personnel. We uphold rigorous criteria for recruitment, conducting thorough background checks for all prospective employees. Regular performance assessments are conducted to verify alignment with our objectives and practices. Employees not adhering to policies may be subjected to disciplinary actions, including but not limited to termination.

Awareness Training

Fennel upholds a Security Awareness initiative integrated into our onboarding process and annual reviews. Participation in this program is mandatory for all employees to guarantee their awareness and comprehension of the policies and procedures they are obligated to follow.

Protecting Customer Data

Network Security

Customer data or code never leaves the single-tenant data plane deployed inside the customer cloud. All data is encrypted in transit and at rest. Data plane has no open ports and all the communication between the data plane and the control plane happens over a secure tunnel initiated by the data plane.

Fennel hosts control plane infrastructure in AWS and leverages their physical and environment security controls. Diagram

Access Control

Fennel's control plane doesn't have the IAM permissions to access any resources in the data plane hosted in the customer's cloud. Access to Fennel's production environment is role based using Google SSO, is authenticated via short-term certificates, and follows the principle of least required privileges at all times.

Elevated levels of access require just-in-time access request approvals such that only the company founders can approve the access requests. Access controls are reviewed at least quarterly.

Access Audits

All accesses to customer environments are logged and are periodically audited. Realtime session activity for all sessions with elevated access levels are recorded.

Data Security


Fennel uses AWS services to keep customer data encrypted during transit and at-rest. Data at rest is encrypted using AES 256-bit encryption and data in transit is protected using TLSv1.2 or higher with requirement of modern cipher suites for all connections.

Data Retention and Disposal

All customer data is backed up nearly continuously in an automated manner.

Our organization adheres to clear-cut policies governing data retention and deletion. We keep customer data for the duration necessary to meet contractual commitments or comply with regulatory standards. Corporate data is retained based on defined periods established by pertinent business stakeholders in alignment with business objectives.

Monitoring and Risk Management

System Monitoring

Fennel invests heavily in extensive monitoring, observability, and alerting for our production environments. We make use of several tools, including but not limited to AWS cloudwatch, Prometheus, Grafana, and PagerDuty.

Alerts are configured for important production systems and functionality. Critical alerts are actioned immediately, with alerts & pages going out to our 24x7x365 on-call rotation.

Subprocessor Management

Fennel employs a risk-based framework to evaluate third-party sub-processors and vendors. We scrutinize their privacy, security, and confidentiality procedures to ensure that they do not compromise our commitment to safeguard customer data and provide a consistently available service.

Vendor assessments occur on an annual basis, considering factors such as the sensitivity of stored data, the significance of our reliance on the service, and the reputation of the service provider. You can find the current list of our sub-processors here.

Change Management

Fennel utilizes an industry standard agile methodology for software development, and performs extensive code reviews and testing before each release.

We adhere to industry best practices, which include mandatory PR approvals, automated code review, a suite of integration and unit tests, and periodic release cuts following manual QA & testing.

Developers are trained to adhere to secure coding guidelines, and are aware of the OWASP Top 10 issues. Security-sensitive code is always reviewed by domain experts.

Incident Management

Security Incidents

Fennel follows a documented Incident Response Plan which is aligned with the SANS Incident Handlers Handbook.

Our plan includes steps for initiating the response plan, escalation to relevant leadership stakeholders, triage, investigation, analysis, mitigation, restoration, and postmortem. Our engineering team works to monitor potential security issues pro-actively, and takes all reports of security-related issues very seriously.

Our 24x7x365 on-call rotation is available for customers to report security incidents. Reports should be made to [email protected], or through other contracted support channels.

Fennel will notify impacted customers of any security issues in a timely fashion.

Disaster Recovery

Fennel has developed a Business Continuity and Disaster Recovery Plan. We perform an annual review and trial run of the plan, and work to ensure that we are able to resume business operations from backup locations, establish communication among core team members, and perform backup restorations successfully.
