Advanced Zero Trust Endpoint Security
CSM Essential is the advanced version of CSM Basic, designed for businesses that require stronger control over how applications, data, and users operate on their endpoints.
Building on everything included in CSM Basic, CSM Essential introduces Zero Trust endpoint security, adding proactive controls that prevent unauthorised activity before it can execute. This approach significantly reduces the risk of ransomware, malicious software, and data exfiltration.
Zero Trust endpoint security applies a deny‑by‑default model, meaning only approved and trusted activity is allowed to run. Anything unknown, unauthorised, or suspicious is blocked by design.
Traditional security tools often focus on detecting threats after they are already running. In contrast, Zero Trust endpoint security assumes no application, process, or action should be trusted by default, even if it originates from inside the network.
This approach helps:
Only approved and trusted applications are allowed to run on endpoints, automatically blocking unknown or unapproved software before it can execute.
Blocking unauthorised processes and suspicious behaviour early, preventing ransomware from reaching the stage where files are encrypted.
Restricting unauthorised access and movement of data, preventing sensitive information from being copied, transferred, or sent outside the organisation.
Preventing threats by design, rather than depending solely on identifying and responding to attacks after they have already started.
Endpoints covered under CSM Essential include the following advanced mitigation measures:
Ensures that only approved and trusted applications are permitted to run on endpoints, automatically blocking unauthorised or unapproved software by default.
Restricts how applications interact with data, files, and system resources, preventing them from accessing or modifying anything beyond what is explicitly required.
Restricts how data can be copied to or accessed from storage devices, preventing unauthorised use of USB drives, external storage, or unsafe locations.
Restricts administrative privileges, ensuring users and applications cannot gain elevated access unless explicitly approved and required.
Restricts endpoint access to only the specific systems and applications a user is authorised to use, continuously verifying identity, device trust, and context before granting access.
These controls work together to enforce least‑privilege access across endpoints, significantly reducing exposure to cyber threats.
This advanced mitigation strategy allows our team to:
By blocking unauthorised encryption activity at its source.
By limiting what software, users, and processes are allowed to do.
By isolating applications and restricting excessive access.
Against modern cyber attacks
With CSM Essential, businesses gain greater visibility and control over endpoint activity, enabling stronger governance and faster response to potential security incidents. Combined with the monitoring and detection capabilities of CSM Basic, Zero Trust controls create a layered and proactive endpoint security posture.
By using a deny‑by‑default approach, CSM Essential helps law firms prevent unauthorised software execution, stop ransomware before encryption begins, and limit data exfiltration, supporting client confidentiality, professional obligations, and risk management expectations.
With strict control over what applications can run, how data can be accessed, and who can elevate privileges, CSM Essential helps accounting firms reduce attack surface, prevent ransomware incidents, and demonstrate due care in protecting client data.
This proactive approach helps professional services firms prevent ransomware, limit data loss, and maintain strong security controls without impacting productivity, enabling secure growth and client confidence.
