Weak router or firewall setup
Many offices use basic router settings that were never properly reviewed. Firewall rules may be too open, remote access may not be controlled, and old equipment may still be protecting the business.
Network and Security Setup
Router, firewall, Wi-Fi, internal network, Microsoft 365, email, endpoint, NAS, backup, and access security setup for small and medium-sized businesses in Japan.
Office Security Foundation
Is Your Office IT Environment Really Protected?
Many small and medium-sized companies use email, Wi-Fi, cloud storage, Microsoft 365, laptops, printers, shared folders, NAS devices, and remote access every day. Over time, the environment can become disorganized, outdated, and risky.
You may not notice the problem until something goes wrong: a phishing email, hacked account, failed backup, slow Wi-Fi, network outage, unsafe remote access, or an employee who still has access after leaving the company.

Common Risks
Common IT Problems Many Companies Face
Small configuration gaps and old operating habits can create downtime, data exposure, recovery cost, and trust issues.
Unsecured Wi-Fi and guest access
Staff, guests, vendors, printers, NAS devices, and office equipment should not all share the same open network. A proper setup separates staff access, guest Wi-Fi, printers, storage devices, and business systems.
Poor Microsoft 365 and email security
If Microsoft 365 or business email is not configured properly, users may be exposed to phishing, fake invoices, password theft, account takeover, weak passwords, and unsafe sharing settings.
Unsafe NAS or shared storage setup
NAS devices are useful for small offices and professional service companies, but access, permissions, remote access, updates, and backup must be managed correctly.
Too many people have access
Former employees, old vendors, temporary staff, and unnecessary admin accounts may still have access to company systems, shared folders, cloud apps, or NAS storage.
No clear backup or recovery plan
Many businesses believe their files are backed up, but they have never tested the backup. If ransomware, accidental deletion, or system failure happens, recovery may be slow or impossible.
Old PCs, devices, and network equipment
Outdated PCs, routers, switches, Wi-Fi access points, NAS devices, and unsupported software can create security and performance problems.
No network documentation
When documentation is missing, nobody knows where everything is, who manages it, or how to fix it quickly when a problem happens.

Setup Coverage
Our Setup Coverage
Internet, router and firewall
We review and configure the main entry point into your office network, including router settings, firewall rules, VPN access, remote access, and basic protection from unwanted traffic.
Office network structure
We organize the internal network so staff devices, guest Wi-Fi, printers, NAS devices, shared storage, and business systems are not all mixed together.
Wi-Fi and guest access
We set up secure staff Wi-Fi and separate guest access for visitors, vendors, and temporary users.
PCs, laptops and endpoint security
We help protect user devices with endpoint protection, updates, access control, encryption checks, device hardening, and patching support.
Microsoft 365, email and cloud security
We help secure company email and cloud tools with MFA, safer sharing settings, admin account review, password policy checks, mailbox security, and anti-phishing improvements.
NAS and shared storage security
We support NAS and shared storage setup, secure access, user permissions, folder structure, backup planning, remote access review, admin account protection, and device update checks.
User access and permissions
We review who has access to company systems, shared folders, cloud applications, admin accounts, NAS devices, and sensitive business data. The right people should have the right access, nothing more.
Backup and recovery
We review how your company protects important files, cloud data, user devices, NAS storage, and business systems, and help confirm whether backups can actually be restored.
Monitoring, documentation and support
We document your network, devices, access points, admin accounts, NAS settings, vendors, and support process so issues can be managed faster and more clearly.
