Vendor Risk Management: All vendor engagements must be approved by Armis, Infosec, Legal, Finance and Procurement Teams, who review each vendor with respect to risk associated with Armis data and risk associated with vendor relations.  Vendors are otherwise required to enter comprehensive confidentiality and quality controls commitments, commit to comprehensive information security standards, agree to reasonable vendor audits & respond to annual security vendor risk assessment questionnaire

Systems Development and Maintenance: Armis’ policy continuously considers the security properties and implications of applications, systems, and services used or provided by Armis throughout a given project lifecycle.  The policy requires individuals to implement appropriate security measures in applications, systems, and services being developed, commensurate with identified security and concerns.  The Company’s Infosec Team is responsible for providing security-related guidance and risk assessment.  aComprehensive procedure is also in place for code development, code review, Q&A cycle, change request process, code freezing and rollout.

Other Administrative Security Measures

Designated Heads of Information Security Program: The Infosec Team is headed by a designated implementation lead, working closely with a compliance lead to define and execute information security program goals.

Geography-based Customer Data Processing/Storage: Armis has implemented an infrastructure configuration whereby customers may select to store all management console data in certain data centers located in geographies selected by customers.

Internal Audit Program: Armis has implemented an internal audit program, to ensure an organized audit process for the Company’s information security policies, processes, technical measures and practices.

Personnel Security: Armis utilizes a 3rd party service to perform comprehensive background checks of all new hires and contractors with access to customer data, subject to local law limitations.  Such background checks, as allowed by local laws, include criminal history, prior employment, educational background and reference checks.

Technical Security Measures

Encryption Practices: All communications with Armis servers, and among Armis servers in different locations, is encrypted in transmission. 256 bit TLS 1.2 is supported.  All password information is encrypted at rest.  In addition, all customers data is encrypted at rest using AES 256.

Network Security: Customers management consoles servers are isolated such that no access is possible among servers of different customers.  The Armis network is protected by redundant firewalls, commercial-class router technology, regular audits, and a host intrusion detection system on the firewall that monitors malicious traffic and network attacks.

Vulnerability Assessment and Pen-Testing: Armis conducts annual, comprehensive penetration testing by a top-tier third party service, including penetration testing our SAAS and agents (black and grey box), corporate infrastructure penetration testing and social targeted attack, and public website automatic testing for open vulnerabilities.  A licensed tool is used to perform periodic network vulnerability assessment on all servers in corporate networks as well as CSP cloud.

MFA: Multi-factor authentication is enabled for access to all critical systems, as well as all admin-level accounts.

Multi-factor authentication and Single-Sign-On (SAML2) systems are implemented with respect to all in-product accesses, as well as Company security devices.

Physical Security Measures

Data Center Perimeter Security: Armis utilizes fully managed data centers from Amazon Web Services (AWS).  These data centers are geographically distributed and employ a variety of best-in-class physical security measures.  The standard physical security controls at each Data Center consist of reliable, well-tested technologies that follow generally accepted industry best practices: custom-designed electronic card access control systems, alarm systems, biometric identification systems, interior and exterior cameras, and a 24X7X365 presence of security guards.  Access to areas where systems or system components are installed or stored is restricted to personnel whose identities are verified through biometric security measures and who have gone through background checks.  Such areas are segregated from general office and public areas.

Access to Armis offices is protected via custom-designed electronic card access control systems including individually-assigned cards and access logging, round-the-clock interior and exterior surveillance, close circuit cameras and alarm systems. We also maintain important contact information with local emergency agencies.

Data Privacy

Because Armis’ collection of assets data and activity is focused on system-level analysis, the majority of the data Armis collects does not include any personally identifiable information, or information which may lead to the identification of a unique individual (PII).  The Customer Data collected by the Platform that may constitute PII including: assets ID and User Names (as assigned by Customers’ IT function); limited number of customers employees’ names, emails (for admin login purposes as well as communication and alerts to customers’ admins); IP addresses;.

As part of its data privacy compliance plan, Armis has implemented a system configuration which allows customers to choose specific geographic data centers where they can store all management console data.  For example, European customers can choose to store all their management console data in Armis’s CSP data centers in Frankfurt, Germany.

Armis continuously updates its Privacy Policy and privacy practices, achieving timely compliance with the European General Data Protection Regulation (GDPR) and California Consumer Privacy Act (CCPA) and implementing a host of data privacy compliance steps to ensure continued compliance with prevalent data privacy legislation.  Such practices include, among other things, accountable management of all PII processed by Armis on behalf of its customers and employees, mapping and documentation of all PII processing, privacy-specific training, breach notification/remediation process, PII access/review/export requests policy and process, appointment of a data privacy officer, permanent deletion of PII once no longer needed to provide the Armis Solutions, and continuous monitoring of emerging data privacy legislation in geographies where Armis does business.
