To the Management of Kastle Systems, Inc.:

We have examined Kastle Systems, LLC’s (“Kastle”) accompanying assertion titled “Assertion of Kastle Systems, LLC’s Management” (“assertion”) that the controls within Kastle’s Managed Security Services System (“system”) were effective throughout the period January 1, 2021 through December 31, 2021, to provide reasonable assurance that Kastle’s service commitments and system requirements were achieved based on the trust services criteria relevant to security, availability and confidentiality (“applicable trust services criteria”) set forth in TSP section 100, 2017 Trust Services Criteria for Security, Availability, Processing Integrity, Confidentiality, and Privacy (AICPA, Trust Services Criteria).

Service Organization’s Responsibilities
Kastle is responsible for its service commitments and system requirements and for designing, implementing, and operating effective controls within the system to provide reasonable assurance that Kastle’s service commitments and system requirements were achieved. Kastle has also provided the accompanying assertion about the effectiveness of controls within the system. When preparing its assertion, Kastle is responsible for selecting, and identifying in its assertion, the applicable trust service criteria and for having a reasonable basis for its assertion by performing an assessment of the effectiveness of the controls within the system.

Service Auditor’s Responsibilities
Our responsibility is to express an opinion, based on our examination, on whether management’s assertion that controls within the system were effective throughout the period to provide reasonable assurance that the service organization’s service commitments and system requirements were achieved based on the applicable trust services criteria. Our examination was conducted in accordance with attestation standards established by the American Institute of Certified Public Accountants. Those standards require that we plan and perform our examination to obtain reasonable assurance about whether management’s assertion is fairly stated, in all material respects. We believe that the evidence we obtained is sufficient and appropriate to provide a reasonable basis for our opinion.

Our examination included:

• Obtaining an understanding of the system and the service organization’s service commitments and system requirements

• Assessing the risks that controls were not effective to achieve Kastle’s service commitments and system requirements based on the applicable trust services criteria

• Performing procedures to obtain evidence about whether controls within the system were effective to achieve Kastle’s service commitments and system requirements based on the applicable trust services criteria.

Our examination also included performing such other procedures as we considered necessary in the circumstances.

Inherent Limitations
There are inherent limitations in the effectiveness of any system of internal control, including the possibility of human error and the circumvention of controls. Because of their nature, controls may not always operate effectively to provide reasonable assurance that the service organization’s service commitments and system requirements were achieved based on the applicable trust services criteria. Also, the projection to the future of any conclusions about the effectiveness of controls is subject to the risk that controls may become inadequate because of changes in conditions or that the degree of compliance with the policies or procedures may deteriorate.

In our opinion, management’s assertion that the controls within Kastle’s Managed Security Services System were effective throughout the period January 1, 2021 through December 31, 2021, to provide reasonable assurance that Kastle’s service commitments and system requirements were achieved based on the applicable trust services criteria, is fairly stated, in all material respects.

We are responsible for designing, implementing, operating, and maintaining effective controls within Kastle’s Managed Security Services System (“system”) throughout the period January 1, 2021 through December 31, 2021, to provide reasonable assurance that Kastle’s service commitments and system requirements relevant to security, availability, and confidentiality were achieved. Our description of the boundaries of the system is presented in this report and identifies the aspects of the system covered by our assertion.

We have performed an evaluation of the effectiveness of the controls within the system throughout the period January 1, 2021 through December 31, 2021, to provide reasonable assurance that Kastle’s service commitments and system requirements were achieved based on the trust services criteria relevant to security, availability, and confidentiality (“applicable trust services criteria”) set forth in TSP section 100, 2017 Trust Services Criteria for Security, Availability, Processing Integrity, Confidentiality, and Privacy (AICPA, Trust Services Criteria). Kastle’s objectives for the system in applying the applicable trust services criteria are embodied in its service commitments and system requirements relevant to the applicable trust services criteria.

There are inherent limitations in any system of internal control, including the possibility of human error and the circumvention of controls. Because of these inherent limitations, a service organization may achieve reasonable, but not absolute, assurance that its service commitments and system requirements are achieved.

We assert that the controls within the system were effective throughout the period January 1, 2021 through December 31, 2021, to provide reasonable assurance that Kastle’s service commitments and system requirements were achieved based on the applicable trust services criteria.

Changes to the System during the Period

During the audit period, Kastle investigated a few incidents related to its systems and applications performance and security controls. These incidents were promptly responded to and mitigated.

This description covers Kastle’s managed security services system.

Components of the System
The system is comprised of the following five components:

• Infrastructure (facilities, equipment, and networks)

• Software (systems, applications, and utilities)

• People (developers, operators, users, and managers)

• Procedures (automated and manual)

• Data (transactions streams, files, databases, and tables)

The following sections of this description define each of these five components comprising Kastle’s Managed security services system and other relevant aspects of Kastle’s control environment, risk assessment process, information and communication systems, and monitoring controls.

Kastle Systems is headquartered in Falls Church, Virginia. Kastle Systems also has offices in Atlanta, Los Angeles, San Francisco, Houston, Dallas, Chicago, Miami, New York, Philadelphia and Sydney, Australia. Physical and logical security controls are uniform across all Kastle locations. Access to every office, computer machine room, and other Kastle work areas containing sensitive information is physically restricted. During non-working hours, workers in areas containing sensitive information lock-up all information. All Kastle computer and network equipment is physically secured at all times. Local area network servers and other multi-user systems are placed in locked cabinets, locked closets, or locked computer rooms. Computer and network gear may not be removed from Kastle offices unless the involved person has obtained permission from management.

  • Internal Network Connections – All Kastle computers that store sensitive information and that are permanently or intermittently connected to internal computer networks have a password-based access control system approved by the Information Security department. Regardless of the network connections, all stand-alone computers handling sensitive information also employ an approved password-based access control system. Multi-user systems throughout Kastle employ automatic log-off systems that automatically terminate a user’s session after a defined period of inactivity and require the user to re-log on to regain access.
  • External Network Connections – All in-bound session connections to Kastle computers from external networks are protected with an approved password access control system. Kastle workers must not establish connections with external networks including Internet service providers unless these connections have been approved by the Information Security department. Kastle Systems also requires that Multi Factor Authentication is required for external access to the Kastle network.
  • Electronic Mail – All Kastle business communications sent by electronic mail are sent and received using an approved electronic mail address. A personal Internet service provider electronic mail account or any other electronic mail address cannot be used for Kastle business unless a worker obtains management approval.
  • Computer Endpoint Security – All personal computer users have the current versions of approved endpoint security software enabled on their computers. Endpoint security software is used to scan all software and data files coming from either third parties or other Kastle groups. This scanning takes place before new data files are opened and before new software is executed. Workers cannot bypass or turn off the scanning processes that could prevent the transmission of viruses or other malware.
  • Computer Malware Eradication – If workers suspect infection by a computer malware, they must immediately stop using the involved computer and call the Kastle help desk. The infected computer must be immediately isolated from internal networks. Users must not attempt to eradicate malware themselves. Qualified Kastle staff or consultants must complete this task in a manner that minimizes both data destruction and system downtime.
  • Formal Change Control – All multi-user computer and communications systems used for production processing employ a documented change control process that is used to ensure that only authorized changes are made. This change control procedure must be used for all significant changes to production system software, hardware, communications links, and procedures.



  • Software Sources – Kastle computers and networks must not run software that comes from sources other than other Kastle departments, knowledgeable and trusted user groups, well-known systems security authorities, or established computer, network, or commercial software vendors. Software downloaded from electronic bulletin boards, shareware, public domain software, and other software from untrusted sources must not be used unless it has been subjected to a rigorous testing regimen approved by the Information Technology department.

  • Internet Access – Workers are provided with Internet access to perform their job duties, but this access may be terminated at any time at the discretion of a worker’s supervisor. Internet access is monitored to ensure that workers are not inappropriately visiting sites unrelated to their jobs, and also to ensure that they continue to be in compliance with security policies. Workers must take special care to ensure that they do not represent Kastle on Internet discussion groups and in other public forums, unless they have previously received top management authorization to act in this capacity. All information received from the Internet should be considered suspect until confirmed by reliable sources. Workers must not place Kastle material on any publicly accessible computer system such as the Internet the Information Owner has approved the posting. The establishment of Internet pages is separately handled by an approval process involving the Director of IT. Sensitive information, including passwords and credit card numbers, must not be sent across the Internet unless the communication is secured through secure transport protocols.

Information Technology Department
The Information Technology department is the  central point of contact for all information security matters at Kastle Systems. Acting as internal technical consultants, it is this department’s responsibility to create workable information security compromises that take into consideration the needs of users, custodians, owners, and selected third parties. Reflecting these compromises, this department defines information security standards, procedures, policies, and other requirements applicable to the entire organization. Information Security must handle all access control administration activities, monitor the security of Kastle information systems, and provide information security training and awareness programs to Kastle workers. The department is responsible for periodically providing management with reports about the current state of information security at Kastle. While information systems contingency planning is the responsibility of information custodians, the Information Technology department must provide technical consulting assistance related to emergency response procedures and disaster recovery. The Information Technology department is also responsible for organizing a computer emergency response team to promptly respond to virus infections, hacker break-ins, system outages, and similar information security problems.
