--- The era when even small and medium-sized enterprises are targeted, ransomware countermeasures are urgent ---
Ransomware attacks are steadily spreading not only to large corporations but also to small and medium-sized enterprises. In fact, cases of damage are increasing regardless of company size, including intrusions via business partners and supply chains, and compromises originating from emails and authentication information. Especially for Microsoft 365, precisely because it is deeply integrated into daily operations, the scope of what needs to be protected is wide, requiring integrated measures that include email, IDs, devices, and file sharing. Furthermore, with the preparation for a supply chain security assessment system scheduled to start around the end of fiscal year 2026, small and medium-sized enterprises are also required to visualize and raise their level of countermeasures.
--- For small IT departments, measures are "fragmented," making it difficult to decide where to start ---
Ransomware countermeasures require multiple measures such as MFA, device management, and detection/blocking after infection. However, for small IT departments, operating these with separate products is not realistic.
- No dedicated staff
- Settings are person-dependent
- Management is fragmented by tool
- Unable to prioritize where to start countermeasures
As a result, individual responses accumulate without a clear overall picture, making policy inconsistencies and missed settings more likely.
--- By integrating with Microsoft, achieve "easy, confusion-free operation" and "robust, sustainable security" measures ---
The approach to solve these challenges of "fragmented measures and not knowing where to start" is to centralize security measures with Microsoft products. With authentication management by Entra ID, unauthorized logins are prevented by MFA and conditional access, device status is centrally managed and controlled by Intune, and in the event of an infection, Defender for Endpoint can cover detection, blocking, and response, preventing over 99% of attacks. By integrating authentication, devices, and post-infection response with Microsoft, instead of having them separately, small IT departments can achieve simpler and more robust operations that are easier to manage.
OrangeOne supports the introduction of such configurations in a way that is easy for small and medium-sized enterprises, offering two introduction styles: a hands-on support plan for companies that want to retain know-how while keeping costs down, and an outsourced plan for companies that want to minimize the burden on their staff and ensure reliable implementation.
--- Recommended for these individuals ---
- Companies with concerns such as "small IT department" or "not knowledgeable about security"
- Companies that urgently want to strengthen their ransomware attack preparedness in preparation for the "security assessment system for strengthening supply chains"
- Small and medium-sized enterprises that want to strengthen security while reducing operational burden
We offer hands-on/outsourced implementation support tailored to your resources. We will set up authentication/device management and EDR operations in the shortest possible time.
