Security Policy
Last Updated: October 27, 2023
This Messangi Security Policy (“Security Policy”) is incorporated into and made a part of the agreement between Messangi and Customer covering Customer’s use of the Services (as defined below) (“Agreement”).
1. Definitions
“Customer Data” means electronic data and content provided to Messangi by Customer (or at its direction) via the Service.
“ Messangi Services” means the Messangi proprietary SaaS (software as a service) platform specified in the applicable order.
“Security Incident” means any unauthorized access to the Service that results in unauthorized transmission, copy, disclosure, alteration or loss of Customer Data.
2. Purpose
This Security Policy describes Messangi’s security program, security certifications, and technical and organizational security controls to protect (a) Customer Data from unauthorized use, access, disclosure, or theft and (b) the Services. As security threats change, Messangi continues to update its security program and strategy to help protect Customer Data and the Services. As such, Messangi reserves the right to update this Security Overview from time to time; provided, however, any update will not materially reduce the overall protections set forth in this Security Overview. The then-current terms of this Security Overview are available at https://www.messangi.com/legal/security-overview. This Security Overview does not apply to any (a) Services that are identified as alpha, beta, not generally available, limited release, developer preview, or any similar Services offered by Mesangi or (b) communications services provided by telecommunications providers.
3. Security Organization and Program
Messangi maintains a risk-based assessment security program. The framework for Messangi’s security program includes administrative, organizational, technical, and physical safeguards reasonably designed to protect the Services and confidentiality, integrity, and availability of Customer Data. Messangi’s security program is intended to be appropriate to the nature of the Services and the size and complexity of Messangi’s business operations. Messangi has an assigned Security committee that manages Messangi’s security program. There is a team that facilitates and supports independent audits and assessments performed by third parties. Messangi’s security framework is based on the ISO 27001 Information Security Management System and includes programs covering: Policies and Procedures, Asset Management, Access Management, Cryptography, Physical Security, Operations Security, Communications Security, Business Continuity Disaster Recovery Security, People Security, Product Security, Cloud and Network Infrastructure Security, Security Compliance, Third-Party Security, Vulnerability Management, and Security Monitoring and Incident Response. Security is managed at the highest levels of the company, with Messangi’s Security Committee that meets regularly to discuss issues and coordinate company-wide security initiatives. Information security policies and standards are reviewed and approved by this committee at least annually and are made available to all Messangi employees for their reference.
4. Confidentiality
Messangi has controls in place to maintain the confidentiality of Customer Data in accordance with the Agreement. All Messangi employees and contract personnel are bound by Messangi’s internal policies regarding maintaining the confidentiality of Customer Data and are contractually obligated to comply with these obligations.
5. People Security
5.1 Employee Background Checks. Messangi performs background checks on all new employees at the time of hire in accordance with applicable local laws. Messangi currently verifies a new employee’s education and previous employment and performs reference checks. Where permitted by applicable law, Messangi may also conduct criminal, credit, immigration, and security checks depending on the nature and scope of a new employee’s role.
5.2 Employee Training. At least once (1) per year, Messangi employees must complete a security and privacy training which covers Messangi’s security policies, security best practices, and privacy principles. Employees on a leave of absence may have additional time to complete this annual training. Messangi’s dedicated security team also performs phishing awareness campaigns and communicates emerging threats to employees. Messangi has also established an anonymous hotline for employees to report any unethical behavior where anonymous reporting is legally permitted.
6. Third Party Vendor Management
6.1 Vendor Assessment. Messangi may use third party vendors to provide the Services. Messangi carries out a security risk-based assessment of prospective vendors before working with them to validate they meet Messangi’s security requirements. Messangi periodically reviews each vendor in light of Messangi’s security and business continuity standards, including the type of access and classification of data being accessed (if any), controls necessary to protect data, and legal or regulatory requirements. Messangi ensures that Customer Data is returned and/or deleted at the end of a vendor relationship. For the avoidance of doubt, telecommunication providers are not considered subcontractors or third-party vendors of Messangi.
6.2 Vendor Agreements. Messangi enters into written agreements with all of its vendors which include confidentiality, privacy, and security obligations that provide an appropriate level of protection for Customer Data that these vendors may process.

8. Hosting Architecture and Data Segregation
8.1 Amazon Web Services.The Messangi Services are hosted on Amazon Web Services (“AWS”) in the United States of America and protected by the security and environmental controls of Amazon. The production environment within AWS where the Messangi Services and Customer Data are hosted are logically isolated in a Virtual Private Cloud (VPC). Customer Data stored within AWS is encrypted at all times. AWS does not have access to unencrypted Customer Data. More information about AWS security is available at https://aws.amazon.com/security/ andhttps://aws.amazon.com/compliance/shared-responsibility-model/. For AWS SOC Reports, please see https://aws.amazon.com/compliance/soc-faqs/.
8.2 Services. For the Services, all network access between production hosts is restricted, using access control lists to allow only authorized services to interact in the production network. Access control lists are in use to manage network segregation between different security zones in the production and corporate environments. Access control lists are reviewed regularly. Messangi separates Customer Data using logical identifiers. Customer Data is tagged with a unique customer identifier that is assigned to segregate Customer Data ownership. The Messangi APIs are designed and built to identify and allow authorized access only to and from Customer Data identified with customer specific tags. These controls prevent other customers from having access to Customer Data.
9. Physical Security.
AWS data centers are strictly controlled both at the perimeter and at building ingress points by professional security staff utilizing video surveillance, intrusion detection systems, and other electronic means. Authorized staff must pass two-factor authentication (2FA) a minimum of two (2) times to access data center floors. All visitors and contractors are required to present identification and are signed in and continually escorted by authorized staff. These facilities are designed to withstand adverse weather and other reasonably predictable natural conditions. Each data center has redundant electrical power systems that are available twenty-four (24) hours a day, seven (7) days a week. Uninterruptible power supplies and on-site generators are available to provide back-up power in the event of an electrical failure. In addition, Messangi headquarters and office spaces have a physical security program that manages visitors, building entrances, closed circuit televisions, and overall office security. All employees, contractors, and visitors are required to wear identification badges.
10. Security by Design
Messangi follows security by design principles when it designs the Services. Messangi also applies the Messangi Secure Software Development Lifecycle (Secure SDLC) standard to perform numerous security-related activities for the Services across different phases of the product creation lifecycle from requirements gathering and product design all the way through product deployment. These activities include, but are not limited to, the performance of (a) internal security reviews before deploying new Services or code; (b) penetration tests of new Services by independent third parties; and (c) threat models for new Services to detect potential security threats and vulnerabilities.
11. Access Controls
11.1 Provisioning Access. To minimize the risk of data exposure, Messangi follows the principles of least privilege through a team-based-access-control model when provisioning system access. Messangi personnel are authorized to access Customer Data based on their job function, role, and responsibilities, and such access requires approval. Access rights to production environments that are not time-based are reviewed at least semi-annually. An employee’s access to Customer Data is promptly removed upon termination of their employment. In order to access the production environment, an authorized user must have a unique username and password and multi-factor authentication enabled. Before an engineer is granted access to the production environment, access must be approved by management and the engineer is required to complete internal training for such access including training on the relevant team’s systems. Messangi logs high risk actions and changes in the production environment. Messangi leverages automation to identify any deviation from internal technical standards that could indicate anomalous/unauthorized activity to raise an alert within minutes of a configuration change.
11.2 Password Controls. Messangi’s current policy for employee password management follows the NIST 800-63B guidance, and as such, our policy is to use longer passwords, with multi-factor authentication, but not require special characters or frequent changes. When a customer logs into its account, Messangi hashes the credentials of the user before it is stored. A customer may also require its users to add another layer of security to their account by using two-factor authentication (2FA).
12. Change Management
Messangi has a formal change management process it follows to administer changes to the production environment for the Services, including any changes to its underlying software, applications, and systems. Each change is carefully reviewed and evaluated in a test environment before being deployed into the production environment for the Services. All changes, including the evaluation of the changes in a test environment, are documented using a formal, auditable system of record. A rigorous assessment is carried out for all high-risk changes to evaluate their impact on the overall security of the Services. Deployment approval for high-risk changes is required from the correct organizational stakeholders. Plans and procedures are also implemented in the event a deployed change needs to be rolled back to preserve the security of the Services.
13. Encryption
For the Messangi Services, (a) the databases that store Customer Data are encrypted using the Advanced Encryption Standard and (b) Customer Data is encrypted when in transit between Customer’s software application and the Services using TLS v1.2. This means that if a recipient’s email server accepts an inbound TLS v1.1 or higher connection, Messangi will deliver a messangiover a TLS encrypted connection. If a recipient’s email server does not support TLS, Messangi will deliver a message over the default unencrypted connection.
14. Vulnerability Management
Messangi maintains controls and policies to mitigate the risk of security vulnerabilities in a measurable time frame that balances risk and the business/operational requirements. Messangi uses a third-party tool to conduct vulnerability scans regularly to assess vulnerabilities in Messangi cloud infrastructure and corporate systems. Critical software patches are evaluated, tested, and applied proactively. Operating system patches are applied through the regeneration of a base virtual-machine image and deployed to all nodes in the Messangi cluster over a predefined schedule. For high-risk patches, Messangi will deploy directly to existing nodes through internally developed orchestration tools.
15. Penetration Testing
Messangi performs penetration tests and engages independent third-party entities to conduct application-level penetration tests. Security threats and vulnerabilities that are detected are prioritized, triaged, and remediated promptly. Messangi maintains a Bug Bounty Program through Bug Crowd, which allows independent security researchers to report security threats and vulnerabilities on an ongoing basis.
16. Security Incident Management
Messangi maintains security incident management policies and procedures in accordance with NIST SP 800-61. Messangi’s Security Incident Response Team (T-SIRT) assesses all relevant security threats and vulnerabilities and establishes appropriate remediation and mitigation actions. Messangi retains security logs for one hundred and eighty (180) days. Access to these security logs is limited to T-SIRT. Messangi utilizes third-party tools to detect, mitigate, and prevent Distributed Denial of Service (DDoS) attacks.
17. Discovery, Investigation, and Notification of a Security Incident
Messangi will promptly investigate a Security Incident upon discovery. To the extent permitted by applicable law, Messangi will notify Customer of a Security Incident in accordance with the Data Protection Addendum. Security Incident notifications will be provided to Customer via email to the email address designated by Customer in its account.
18. Resilience and Service Continuity
18.1 Resilience. The hosting infrastructure for the Messangi Services (a) spans multiple fault-independent availability zones in geographic regions physically separated from one another and (b) is able to detect and route around issues experienced by hosts or even whole data centers in real time and employ orchestration tooling that has the ability to regenerate hosts, building them from the latest backup.
18.2 Service Continuity. Messangi also leverages specialized tools available within the hosting infrastructure for the Services to monitor server performance, data, and traffic load capacity within each availability zone and colocation data center. If suboptimal server performance or overloaded capacity is detected on a server within an availability zone or colocation data center, these specialized tools increase the capacity or shift traffic to relieve any suboptimal server performance or capacity overload. Messangi is also immediately notified in the event of any suboptimal server performance or overloaded capacity.
19. Customer Data Backups.
Messangi performs regular backups of Customer Data, which is hosted on AWS’s data center infrastructure. Customer Data that is backed up is retained redundantly across multiple availability zones and encrypted in transit and at rest using the Advanced Encryption Standard.
