1 Executive Summary
This Validation Report (VR) documents the National Information Assurance Partnership (NIAP) assessment
of the evaluation of Wickr Enterprise Client 6.10 (the Target of Evaluation, or TOE). It presents the
evaluation results, their justifications, and the conformance results. This VR is not an endorsement of the
TOE by any agency of the U.S. Government and no warranty of the TOE is either expressed or implied.
The evaluation was performed by Leidos Common Criteria Testing Laboratory (CCTL) in Columbia,
Maryland, USA, and was completed in April 2023. The information in this report is largely derived from
the Evaluation Technical Report (ETR) and associated test report written by Leidos. The evaluation
determined that the TOE is Common Criteria Part 2 Extended and Common Criteria Part 3 Extended and
meets the assurance requirements of the following document:
• Protection Profile for Application Software, Version 1.4, 7 October 2021
The Target of Evaluation (TOE) is the Wickr Enterprise Client 6.10.
The Target of Evaluation (TOE) identified in this Validation Report has been evaluated at a NIAP approved
Common Criteria Testing Laboratory using the Common Methodology for IT Security Evaluation (Version
3.1, Rev 5) for conformance to the Common Criteria for IT Security Evaluation (Version 3.1, Rev 5). This
Validation Report applies only to the specific version of the TOE as evaluated. The evaluation has been
conducted in accordance with the provisions of the NIAP Common Criteria Evaluation and Validation
Scheme and the conclusions of the testing laboratory in the evaluation technical report are consistent
with the evidence provided.
The validation team monitored the activities of the evaluation team, provided guidance on technical
issues and evaluation processes, and reviewed the individual work units documented in the ETR and the
Assurance Activities Report (AAR). The validation team found the evaluation demonstrated the product
satisfies all of the Security Functional Requirements (SFRs) and Security Assurance Requirements (SARs)
specified in the Security Target. Therefore the validation team concludes that the testing laboratory’s
findings are accurate, the conclusions justified, and the conformance results are correct. The conclusions
of the testing laboratory in the evaluation technical report are consistent with the evidence produced.
The technical information included in this report was obtained from the Wickr Enterprise Client 6.10
Security Target, Version 1.0, 07 March 2023 and analysis performed by the Validation Team.

3 Assumptions and Clarification of Scope
3.1 Assumptions
The Security Problem Definition, including the assumptions, may be found in the following document:
Protection Profile for Application Software, Version 1.4, 7 October 2021
That information has not been reproduced here and the NDcPP22e should be consulted if there is interest
in that material.
The scope of this evaluation was limited to the functionality and assurances covered in the PP_APP_v1.4
as described for this TOE in the Security Target.
As stated, the ST references PP_APP_v1.4 to which it claims conformance for assumptions about the use
of the TOE. Those assumptions, drawn from the claimed PP, are as follows:
• The TOE relies upon a trustworthy computing platform with a reliable time clock for its execution.
This includes the underlying platform and whatever runtime environment it provides to the TOE.
• The user of the application software is not willfully negligent or hostile, and uses the software in
compliance with the applied enterprise security policy.
• The administrator of the application software is not careless, willfully negligent, or hostile, and
administers the software in compliance with the applied enterprise security policy.
Other functionality included in the product was not assessed as part of this evaluation. All other
functionality provided by the devices needs to be assessed separately, and no further conclusions can be
drawn about their effectiveness.
3.2 Clarification of Scope
All evaluations (and all products) have limitations, as well as potential misconceptions that need clarifying.
This text covers some of the more important limitations and clarifications of this evaluation. Note that:
• As with any evaluation, this evaluation shows only that the evaluated configuration meets the
security claims made, with a certain level of assurance, achieved through performance by the
evaluation team of the evaluation activities specified in the following document:
o Protection Profile for Application Software, Version 1.4, 7 October 2021
• This evaluation covers only the specific software distribution and version identified in this
document, and not any earlier or later versions released or in process.
• The evaluation of security functionality of the product was limited to the functionality specified
in Wickr Enterprise Client 6.10 Security Target, Version 1.0, 07 March 2023. Any additional
security related functional capabilities included in the product were not covered by this
evaluation. In particular, the functionality mentioned in Section 8.2 of this document is excluded
from the scope of the evaluation.
• This evaluation did not specifically search for, nor attempt to exploit, vulnerabilities that were not
“obvious” or vulnerabilities to objectives not claimed in the ST. The CEM defines an “obvious”
vulnerability as one that is easily exploited with a minimum of understanding of the TOE, technical
sophistication, and resources.
• The TOE must be installed, configured, and managed as described in the documentation
referenced in Section 6 of this this report.

Figure 1: Wickr Architecture
Wickr Enterprise Client 6.10 Validation Report Version 1.0
Page 6 of 20
The figure depicts initial communication setup for a call. The direction of the arrows indicates which
system initiates communication. Communication is bi-directional once a connection is established. The
Wickr Client relies on the cryptographic functions of its host platform for data in transit.
4.2 Physical Boundaries
The TOE consists of the Wickr Client application. For this evaluation, the TOE is evaluated on the following
specific platforms:
• Windows:
o Microsoft Surface Laptop 4
o Intel i5-1145G7 (Tiger Lake) processor
o Windows 10 64-bit OS
• macOS:
o MacBook Pro
o Intel i7-9750H (Coffee Lake) processor
o macOS Monterey 12.4 OS
• iOS:
o iPhone 12
o Apple A14 Bionic (ARMv8) processor
o iOS 15.5 OS
• Android:
o Samsung Galaxy S20 FE
o Qualcomm Snapdragon 865 (ARMv8) processor
o Android 12 OS
In addition to the platforms identified above, the TOE’s operational environment includes the following:
• A Wickr Server installed for messaging
• One or more remote Wickr Client instances to establish connections with
• A Workstation with a browser to access the Wickr Server’s Admin Console (Wickr Clients receive
configuration information from a Wickr Server)
• An Update server (public download site).
Wickr Enterprise Client 6.10 Validation Report Version 1.0

5 Security Policy
The TOE enforces the following security policies as described in the ST.
Note: Much of the description of the security policy has been derived from the ST and the Final ETR.
5.1 Cryptographic Support
The TOE uses NIST-validated cryptographic algorithms to secure messaging data in transit. The
cryptographic functions for this are supplied by the host platform. All platform versions of the TOE also
implement their own NIST-validated cryptographic algorithms through OpenSSL to support the protection
of credential data at rest. The TOE relies on platform-provided entropy for random number generator
seeding.
The TOE uses cryptographic functionality to protect stored credential data. This is done through a
combination of TSF-provided cryptography and platform cryptography for all platform versions.
5.2 User Data Protection
The TOE provides cryptographic functionality and also leverages functionality provided by its underlying
OS platforms to secure sensitive data at rest. The TOE uses network resources provided by the underlying
platforms. All platform services are invoked at the direction of the user.
The TOE uses network connectivity to interact with a Wickr Server to establish connections with other
Wickr Clients. The TOE or its platform, depending on platform version, check for updates from an update
server.
5.3 Identification and Authentication
The TOE relies on platform-provided functionality to validate X.509 certificates used to authenticate TLS
servers when establishing trusted communications except in the case where the desktop platform
versions of the TOE (macOS, Windows) are responsible for validating the crlsign bit on any certificate used
to sign a CRL. Certificate validation is performed in accordance with RFC 5280 and CRLs are used for
revocation checking in all cases except for iOS, which uses OCSP.
5.4 Security Management
Wickr Client configuration data is stored locally using mechanisms that are recommended by the
respective platform vendors. The TOE is not installed with default credentials. The Wickr Client applies
configuration settings it obtains from the Wickr Server.
5.5 Privacy
The TOE does not process any personally identifiable information (PII). No transmission of PII occurs that
is not in direct response to user activity.
5.6 Protection of the TSF
The TOE includes measures to integrate securely with its underlying OS platform. The TOE does not
perform explicit memory mapping, nor does it allocate any memory region with both write and execute
permissions. Similarly, the TOE does not write user-modifiable data to directories that contain executable
files. The TOE is compatible with its supported host OS platform when configured in a secure manner. All
platform versions of the TOE are compiled with stack overflow protection.
Wickr Enterprise Client 6.10 Validation Report Version 1.0
Page 8 of 20
The TOE uses a well-defined set of platform APIs and third-party libraries.
The TOE provides the ability for a user to check its version. The TOE platform is used to apply updates.
Updates are delivered in a format that is appropriate for the TOE’s platform. Updates to the TOE are
digitally signed, and the signature is validated prior to installation. The TOE does not modify its own code.
Removal of the application removes all executable code associated with the TOE.
5.7 Trusted Path/Channels
The TOE uses trusted channels to secure data in transit between itself and external entities. The TOE
communicates with the Wickr Server for messaging services and authentication using platform provided
TLS.
Wickr Enterprise Client 6.10 Validation Report Version 1.0

April 2023.
A non-proprietary description of the tests performed and their results is provided in the following
document:
• Assurance Activities Report for Wickr Enterprise Client 6.10, Version 1.0, 5 April 2023
The purpose of the testing activity was to confirm the TOE behaves in accordance with the TOE security
functional requirements as specified in the ST for a product that claims conformance to the following
specification:
• Protection Profile for Application Software, Version 1.4, 7 October 2021.
7.1 Developer Testing
No evidence of developer testing is required in the assurance activities for this product.
7.2 Evaluation Team Independent Testing
The evaluation team devised a test plan based on the test activities specified in the PP. The test plan
described how each test activity was to be instantiated within the TOE test environment. The evaluation
team executed the tests specified in the test plan and documented the results in the team test report
listed above. Independent testing took place at Leidos CCTL facilities in Columbia, Maryland, from
November 2022 to April 2023.
The evaluators received the TOE in the form that customers would receive it, installed and configured the
TOE in accordance with the provided guidance, and exercised the team test plan on equipment configured
in the testing laboratory.
Given the complete set of test results from the test procedures exercised by the evaluators, the testing
requirements for Protection Profile for Application Software were fulfilled.

9 Results of the Evaluation
The results of the evaluation of the TOE against its target assurance requirements are generally described
in this section and are presented in detail in the proprietary Evaluation Technical Report for Wickr
Enterprise Client 6.10 The reader of this VR can assume that all assurance activities and work units
received passing verdicts.
A verdict for an assurance component is determined by the resulting verdicts assigned to the
corresponding evaluator action elements. The evaluation was conducted based upon CC version 3.1,
revision 5 and CEM version 3.1, revision 5, and the specific evaluation activities specified in:
• Protection Profile for Application Software, Version 1.4, 7 October 2021 .
The evaluation determined the TOE satisfies the conformance claims made in the Wickr Enterprise Client
6.10 Security Target, of Part 2 extended and Part 3 extended. The TOE satisfies the requirements specified
in the PP listed above.
The Validators reviewed all the work of the evaluation team and agreed with their practices and findings.
9.1 Evaluation of the Security Target (ST) (ASE)
The evaluation team performed each TSS evaluation activity and ASE CEM work unit. The ST evaluation
ensured the ST contains an ST introduction, TOE overview, TOE description, security problem definition in
terms of threats, policies and assumptions, description of security objectives for the operational
environment, a statement of security requirements claimed to be met by the product that are consistent
with the claimed PP, and security function descriptions that satisfy the requirements.
9.2 Evaluation of the Development (ADV)
The evaluation team performed each ADV evaluation activity and applied each ADV_FSP.1 CEM work unit.
The evaluation team assessed the evaluation evidence and found it adequate to meet the requirements
specified in the claimed PP for design evidence. The ADV evidence consists of the TSS descriptions
provided in the ST and product guidance documentation providing descriptions of the TOE external
interfaces.
9.3 Evaluation of the Guidance Documents (AGD)
The evaluation team performed each guidance evaluation activity and applied each AGD work unit. The
evaluation team determined the adequacy of the operational user guidance in describing how to operate
the TOE in accordance with the descriptions in the ST. The evaluation team followed the guidance in the
TOE preparative procedures to test the installation and configuration procedures to ensure the
procedures result in the evaluated configuration. The guidance documentation was assessed during the
design and testing phases of the evaluation to ensure it was complete.
9.4 Evaluation of the Life Cycle Support Activities (ALC)
The evaluation team performed each ALC evaluation activity and applied each ALC_CMC.1 and ALC_CMS.1
CEM work unit, to the extent possible given the evaluation evidence required by the claimed PP. The
evaluation team ensured the TOE is labeled with a unique identifier consistent with the TOE identification
in the evaluation evidence, and that the ST describes how timely security updates are made to the TOE.
Wickr Enterprise Client 6.10 Validation Report Version 1.0
Page 15 of 20
9.5 Evaluation of the Test Documentation and the Test Activity (ATE)
The evaluation team performed each test activity and applied each ATE_FUN.1 CEM work unit. The
evaluation team ran the set of tests specified by the claimed PP and recorded the results in the Test
Report, summarized in the AAR.
9.6 Vulnerability Assessment Activity (AVA)
The evaluation team performed each AVA evaluation activity and applied each AVA_VAN.1 CEM work
unit. The evaluation team performed a vulnerability analysis following the processes described in the
claimed PP. This comprised a search of public vulnerability databases.
The evaluation team performed a search of the National Vulnerability Database (https://nvd.nist.gov/).
Searches were performed on 4/5/2023, using the following search terms:
• Wickr
• Encrypted Service
• zero trust
• OpenSSL 1.0.2zg
• OpenSSL 2.0.16
• symcrypt
• Apple coreCrypto Module
• BoringSSL
• Third Party Libraries identified in Section A.2 of the Security Target
The results of these searches did not identify any vulnerabilities that are applicable to the TOE. The
conclusion drawn from the vulnerability analysis is that no residual vulnerabilities exist that are
exploitable by attackers with Basic Attack Potential as defined by the Certification Body in accordance
with the guidance in the CEM.
9.7 Summary of Evaluation Results
The evaluation team’s assessment of the evaluation evidence demonstrates that the claims in the ST are
met, sufficient to satisfy the assurance activities specified in the claimed PP. Additionally, the evaluation
team’s testing also demonstrated the accuracy of the claims in the ST.
