Nosto Security Standards

1. Information Security Program

Nosto will maintain an information security program in accordance with Article 32 of the GDPR (including the adoption and enforcement of internal policies and procedures) designed to (a) help the Customer secure Customer Data against accidental or unlawful loss, access or disclosure, (b) identify reasonably foreseeable and internal risks to security and unauthorized access to the Nosto Infrastructure, and (c) minimize security risks, including through risk assessment and regular testing. Nosto will designate one or more employees to coordinate and be accountable for the information security program. The information security program will include the following measures:

a. the pseudonymization and encryption of personal data;

b. the ability to ensure the ongoing confidentiality, integrity, availability and resilience of processing systems and services;

c. the ability to restore the availability and access to personal data in a timely manner in the event of a physical or technical incident;

d. a process for regularly testing, assessing and evaluating the effectiveness of technical and organizational measures for ensuring the security of the processing.

1.1. Security of Nosto Infrastructure

1.1.1. Data Centers. All servers are hosted by Amazon Web Services (“AWS”) which is among the biggest cloud computing providers and has a long track record running data centers reliably and securely. AWS manages data center infrastructure, physical security and continuity as a data center provider. For more details, please see the AWS security whitepaper. The Service is run in a virtual private cloud (“VPC”) where access to each subsystem is limited with a firewall and accessing a subsystem requires a virtual private network (“VPN”) connection with time-based one-time password (“TOTP”) multi-factor authentication. Accessing the AWS resources via an API requires authentication to AWS Identity and Access Management (“IAM”) with access key and secret access key. IAM authentication with a username and password requires TOTP multifactor authentication.

1.1.2. Access to Nosto Infrastructure. The Nosto Infrastructure Network will be accessible to Nosto Personnel, contractors and any other persons as necessary to provide the Services (such as Sub-processors).  Nosto will maintain access controls as described above in Section 1.1.1 of this Schedule 2 (Nosto Security Standards) and policies to manage what access is granted to the Nosto Infrastructure from each network connection and for each user. Access permissions are granted only to those employees for whom access to the Nosto Infrastructure Network is necessary in order to perform their tasks.

1.1.3. Auditing. Audit logging of the Nosto Infrastructure is done on multiple levels, including activities performed by Nosto Personnel, Customers or system components. Attempts to modify audit configurations while the audit collection functions are active are logged. These logs are forwarded to a remote and centralized logging system where they can be monitored. Logs are saved in dedicated database cluster that is replicated for redundancy and availability. Configuration changes to AWS resources are tracked; these logs include detailed information about API calls to AWS resources.

1.2. Physical Security

1.2.1. Physical Access Controls. Access to Nosto facilities (the “Facilities“)does not grant any access to the Nosto Infrastructure. Physical barrier controls are used to prevent unauthorized entrance to the Facilities. Passage through the physical barriers at the Facilities requires either electronic access control validation (e.g., card access systems, etc.) or validation by human security personnel (e.g., contract or in-house security guard service, receptionist, etc.). Visitors at the Facilities are escorted by authorized employees or contractors.

1.2.2. Unlimited Employee and Contractor Access. Nosto provides access to the Facilities to those employees and contractors who have a legitimate business need for such access privileges. When an employee or contractor no longer has a business need for the access privileges assigned to them, access privileges are promptly revoked, even if the employee or contractor continues to be an employee or contractor of Nosto or its affiliates.

1.2.3. Physical Security Protections.  All access points (other than main entry doors) are maintained in a secured (locked) state. Nosto also maintains electronic intrusion detection systems designed to detect unauthorized access to the Facilities, including motion detection devices designed to detect individuals attempting to gain access to the Facilities. All physical access to the Facilities by employees and contractors is logged.

2. Continued Evaluation

Nosto will conduct periodic reviews of the security of the Nosto Infrastructure and adequacy of its information security program as measured against industry security standards and its policies and procedures. Nosto will continually evaluate the security of its Nosto Infrastructure and associated Services to determine whether additional or different security measures are required to respond to new security risks or findings generated by the periodic reviews
