Cloudsilicon is a managed cybersecurity service provider targeting small and mid-sized businesses with 5 to 200 endpoints. It offers three tiers of endpoint protection under the "Office Antivirus" product line, managed via global security operations centres. **Office Antivirus Essentials** — The base tier provides endpoint protection using a multi-layered approach combining signature-based detection, machine learning, and behavioural analysis. It includes ransomware protection with automatic blocking and file remediation, network attack defence covering inbound/outbound/lateral traffic, web protection and content filtering, and risk management/hardening tools. Management is handled via a centralised cloud-based console. Supports Windows, macOS, and Linux. **Office Antivirus EDR** — Builds on Essentials by adding Endpoint Detection and Response (EDR) for telemetry correlation and attack chain visibility, HyperDetect (a machine learning layer for fileless and evasive threats), and Automated Sandbox Analysis for detonating and inspecting suspicious files in an isolated environment. All Essentials features are retained. **Office Antivirus MDR** — The top tier adds a fully managed detection and response service with 24/7/365 analyst-driven monitoring, triage, investigation, and incident response. Security analysts handle threat containment, isolation, and remediation based on pre-approved actions. Retains all EDR and Essentials capabilities including HyperDetect and Automated Sandbox Analysis. All tiers are delivered with easy monthly payments and managed through a unified, cloud-enabled console.
