ANNEX II TO THE DPA

Semrush may update or modify these security measures from time to time provided that such updates and modifications do not result in the degradation of the overall security of the Services.

A. Data Center

1. Semrush stores all production data in physically secure data centers.
2. Infrastructure systems have been designed to eliminate single points of failure and minimize the impact of anticipated environmental risks. Dual circuits, switches, networks or other necessary devices help provide this redundancy. The Services are designed to allow Semrush to perform certain types of preventative and corrective maintenance without interruption. All environmental equipment and facilities have documented preventative maintenance procedures that detail the process for and frequency of performance in accordance with the manufacturer’s or internal specifications. Preventative and corrective maintenance of the data center equipment is scheduled through a standard change process according to documented procedures.
3. The data center electrical power systems are designed to be redundant and maintainable without impact to continuous operations, 24 hours a day, and 7 days a week. In most cases, a primary as well as an alternate power source, each with equal capacity, is provided for critical infrastructure components in the data center. Backup power is provided by various mechanisms such as uninterruptible power supplies (UPS) batteries, which supply consistently reliable power protection during utility brownouts, blackouts, over voltage, under voltage, and out-of-tolerance frequency conditions. If utility power is interrupted, backup power is designed to provide transitory power to the data center, at full capacity, for up to 10 minutes until the diesel generator systems take over. The diesel generators are capable of automatically starting up within seconds to provide enough emergency electrical power to run the data center at full capacity typically for a period of days.
4. Semrush has designed and regularly plans and tests its business continuity planning/disaster recovery checks.
5. When user data is copied electronically by Semrush outside the data center, appropriate physical security is maintained, and the data is encrypted at all times.

B. Access Control

1. Preventing Unauthorized Services Access:
   1. Semrush hosts its Service with outsourced cloud infrastructure providers.
   2. Additionally, Semrush maintains contractual relationships with vendors in order to provide the Service in accordance with DPA. Semrush relies on contractual agreements, privacy policies, and vendor compliance procedures in order to protect data processed or stored by these vendors.
   3. Semrush hosts its Services infrastructure with multi-tenant, outsourced infrastructure providers.
   4. Semrush implemented a uniform password policy for its Services and correspondent tools and features. All passwords must fulfil defined minimum requirements and are stored in encrypted form. Users who interact with the Services via the user interface must authenticate before accessing non-public user data.
   5. User data is stored in multi-tenant storage systems accessible to users via only application user interfaces and application programming interfaces. Users are not allowed direct access to the underlying application infrastructure. The authorization model in each of the tools and features of the Services is designed to ensure that only the appropriately assigned individuals can access relevant features, views, and customization options. Authorization to data sets is performed through validating the user’s permissions.
   6. Public Services APIs may be accessed using an API key.
2. Preventing Unauthorized Services Use. Semrush utilizes the following access controls and detection capabilities for the internal networks that support its Services:
   1. Network access control mechanisms are designed to prevent network traffic using unauthorized protocols from reaching the Services infrastructure. The technical measures implemented differ between infrastructure providers and include Virtual Private Cloud (VPC) implementations, security group assignment, and traditional firewall rules.
   2. Semrush implemented a Web Application Firewall (WAF) solution to protect internet-accessible applications. The WAF is designed to identify and prevent attacks against publicly available network services.
   3. Security reviews of the parts of code stored in Semrush source code repositories are performed, checking for coding best practices and identifiable software flaws.
   4. Semrush conducts penetration tests annually. The intent of the penetration tests is to identify and resolve foreseeable attack vectors and potential abuse scenarios.
   5. A bug bounty program invites and incentivizes independent security researchers to ethically discover and disclose security flaws. Semrush implemented a bug bounty program in an effort to widen the available opportunities to engage with the security community and improve the Services defenses against sophisticated attacks.
3. Authorization Requirements. A subset of Semrush and Semrush affiliates’ employees have access to user data via controlled interfaces. The intent of providing access to a subset of employees is to provide effective customer support, to troubleshoot potential problems, to detect and respond to security incidents and implement data security. Semrush and Semrush affiliates’ employees are required to conduct themselves in a manner consistent with the Semrush guidelines regarding confidentiality, business ethics, appropriate usage, and professional standards.

C. Transmission Control

Semrush makes HTTPS encryption (also referred to as SSL or TLS) available on every one of its login interfaces. Semrush HTTPS implementation uses industry standard algorithms and certificates.

D. Input Control

1. Semrush designed its infrastructure to log extensive information about the system behavior, traffic received, system authentication, and other application requests partly. Internal systems aggregate log data and alert appropriate employees of malicious, unintended, or anomalous activities. Semrush personnel, including security, are responsive to known incidents.
2. Semrush maintains a record of known security incidents that includes description, dates and times of relevant activities, and incident disposition. Suspected and confirmed security incidents are investigated by security, operations, or support personnel; and appropriate resolution steps are identified and documented. For any confirmed incidents, Semrush will take appropriate steps to minimize User damage or unauthorized disclosure.
3. If Semrush becomes aware of unlawful access to Semrush data stored within its Services, Semrush will:
   1. notify the affected Users of the incident;
   2. provide a description of the steps Semrush is taking to resolve the incident; and
   3. provide status updates to the User contact, as Semrush deems necessary.
4. Notification(s) of incidents, if any, will be delivered to one or more of the User’s contacts in a form Semrush selects, which may include via email or telephone.

E. Availability Control

1. The infrastructure providers use commercially reasonable efforts to ensure a minimum of 99.8% uptime. The providers maintain a minimum of N+1 redundancy to power, network, and HVAC services.
2. Backup and replication strategies are designed to ensure redundancy and fail-over protections during a significant processing failure. Semrush data is backed up to multiple durable data stores and replicated across multiple availability zones. Semrush uses commercially reasonable efforts to create frequent, encrypted back-up copies of Protected Data and these are stored in geographically separate locations.
3. Where feasible, production databases are designed to replicate data between no less than 1 primary and 1 secondary database. All databases are backed up and maintained using at least industry standard methods.

The Services are designed to ensure redundancy and seamless failover. The server instances that support the Services are also architected with a goal to prevent single points of failure. This design assists Semrush operations in maintaining and updating the Services applications and backend while limiting downtime.
