WhatsApp **01712-644590**. --- Dhaka's small business landscape is booming, but most office owners think about network security only after a problem strikes. A ransomware attack locks files. An employee leaks confidential data. The WiFi gets hacked and bandwidth stalls. By then, damage is already done. BAYAS prevents these incidents. We design and install network security systems tailored to Dhaka offices — from single-room home offices to multi-floor commercial spaces. Our approach combines enterprise-grade protection with transparent pricing and same-day response across the city. This guide explains what office network security entails, common threats facing Dhaka businesses, our installation process, and pricing for each service tier. Whether you are running a 5-person startup in Banani or a 50-person trading firm in Tejgaon, these principles apply to keeping your office safe. --- ## Why Office Network Security Matters More Than Ever in Dhaka The threat landscape in Dhaka has shifted dramatically in 2025–2026. Cybercrime is no longer limited to tech-savvy attackers targeting large corporations. Small business networks are increasingly vulnerable, and Dhaka's dense urban environment introduces unique risks. **Ransomware attacks on Bangladeshi businesses increased by 40% in 2025**, according to the Bangladesh Computer Council. Many victims are small offices with no firewall or outdated antivirus. Once encrypted, files remain locked until a ransom — often $500–$5,000 — is paid. Most businesses never recover their data. **WiFi hacking is common in Dhaka's commercial buildings.** Open or weakly secured networks in shared office spaces make it easy for anyone nearby to intercept unencrypted traffic. Customer payment data, employee login credentials, and business communications can all be captured. **Insider threats account for nearly 30% of security breaches** in small businesses. Employees accessing sensitive files without authorization, USB devices carrying malware, and poor password practices all contribute to office data loss. **Load-shedding and power surges** threaten both physical security equipment and network infrastructure. When power returns after load-shedding, voltage spikes can damage routers, switches, and CCTV systems — leaving offices unprotected exactly when they need security most. These risks make professional network security setup not a luxury but a necessity for any Dhaka business that handles digital data, accepts online payments, or operates cloud-based tools. --- ## Common Office Network Security Threats in Dhaka Understanding the threats your office faces helps you choose the right protection strategy. Here are the most prevalent issues we encounter during [computer home service](/services/computer-home-service-dhaka) visits across Dhaka: ### 1. Unpatched Software and Operating Systems Many Dhaka offices run Windows 10 machines that are years past end-of-support, receiving no security patches from Microsoft. These systems are open doors for malware and ransomware. Without regular updates, known vulnerabilities remain exploitable indefinitely. ### 2. Weak or Shared WiFi Passwords Office networks in Dhaka often use simple passwords like "office123" or share the same WiFi credentials among all employees — including temporary staff and visitors. When someone leaves the company, their access persists unless you manually revoke it. This is a leading cause of data breaches. ### 3. No Network Segmentation Small offices typically run all devices on a single network — computers, phones, printers, security cameras, and guest WiFi all share the same network segment. If one device gets infected, malware spreads laterally across every connected system. Network segmentation isolates critical assets. ### 4. Missing or Misconfigured Firewalls Firewalls act as barriers between your office network and the internet. Many businesses either skip firewalls entirely or rely on basic ISP-provided routers with default settings that leave ports exposed. Proper firewall configuration blocks unauthorized inbound and outbound traffic. ### 5. Inadequate CCTV Surveillance Integration CCTV cameras are essential for physical security, but many Dhaka offices install them without integrating them into the network security architecture. Poorly configured CCTV systems create backdoors into the network. Cameras should sit on isolated VLANs with restricted internet access. ### 6. Lack of VPN for Remote Workers Post-2025, hybrid work models are common in Dhaka. Employees working from home access office systems over public WiFi or cellular data — without VPN encryption, sensitive data travels in plain text across untrusted networks. --- ## BAYAS Office Network Security Services We offer comprehensive network security solutions tailored to Dhaka's business environment. Each service includes site assessment, professional installation, and documentation. ### Firewall Configuration and Installation Firewalls are the first line of defense against external threats. We configure both hardware firewalls (for offices with dedicated server rooms) and software firewalls (for smaller setups), ensuring proper rule sets block malicious traffic while allowing legitimate business operations. **What's included:** - Assessment of current network perimeter exposure - Hardware firewall procurement and installation (TP-Link, Fortinet, or Ubiquiti options) - Rule configuration based on your business needs - Port forwarding and DMZ setup for specific applications - Regular rule review and updates **Pricing:** BDT 5,000–12,000 depending on office size and complexity Related: See our [networking service page](/services/networking-service-dhaka) for full connectivity solutions. ### WiFi Security Hardening Weak WiFi security is the easiest attack vector. We upgrade your wireless infrastructure to current standards with strong encryption, hidden SSIDs where appropriate, and guest network isolation. **What's included:** - Current WiFi security audit - WPA3 or WPA2-Enterprise encryption setup - Strong password generation and rotation policy - Guest WiFi isolation (separate network for visitors) - WiFi coverage optimization using [router setup and troubleshooting](/blog/wifi-router-setup-troubleshooting-dhaka) best practices - Signal strength testing across your office space **Pricing:** BDT 3,000–8,000 depending on AP count and coverage area ### VLAN Segmentation Virtual LANs divide your network into isolated segments. Your servers, employee workstations, IoT devices, and guest WiFi each get their own secure zone. If a guest device gets infected, the malware cannot reach your accounting server. **What's included:** - Network topology assessment - VLAN design based on department and function - Managed switch configuration (required for VLANs) - Inter-VLAN routing rules - Testing and documentation **Pricing:** BDT 6,000–15,000 including managed switch if needed ### CCTV Network Integration [CCTV camera installation and repair](/services/cc-camera-repair-service-dhaka) for offices requires security-conscious integration. Cameras should not compromise your network — they should enhance your physical security without creating digital vulnerabilities. **What's included:** - Network architecture review for CCTV deployment - Dedicated CCTV VLAN setup - NVR (network video recorder) placement and configuration - Remote viewing setup with encrypted connections - Camera positioning for maximum coverage with minimal blind spots **Pricing:** BDT 8,000–25,000 depending on camera count and system complexity ### VPN Setup for Remote Access Office VPNs allow employees to securely access office resources from home, coffee shops, or while traveling. Without VPN, remote workers expose their connections to interception on public networks. **What's included:** - VPN server configuration (OpenVPN, WireGuard, or IPsec) - Certificate management and key distribution - Client setup on employee devices - Bandwidth and access policy configuration - Documentation for your IT team **Pricing:** BDT 4,000–10,000 for standard small office VPN deployment ### Security Audit and Maintenance Contracts Ongoing maintenance keeps your network secure as threats evolve. Our monthly contracts include scheduled audits, firmware updates, log reviews, and priority emergency response. **What's included:** - Monthly security scan and vulnerability assessment - Firmware updates for all network equipment - Log review for suspicious activity - Password policy enforcement - Quarterly on-site visit for hands-on inspection - Priority WhatsApp support (respond within 2 hours during business hours) **Pricing:** BDT 3,000–8,000 per month depending on office size and device count --- ## The BAYAS Office Security Installation Process Every [computer repair service in Dhaka](/services/computer-repair-service-dhaka) engagement follows a structured process to ensure nothing is missed: ### Phase 1: On-Site Assessment (1–2 Hours) Our technician visits your office to map your current network infrastructure.

Implement password managers for employees. Change default passwords on all network equipment immediately. ### Limit Administrative Access Not every employee needs admin rights. Restrict administrative access to IT staff and department heads. Use standard user accounts for daily work. ### Install Endpoint Protection Every computer, phone, and tablet connecting to your office network should have updated antivirus or endpoint protection software. See our [virus removal guide](/blog/virus-removal-dhaka) for details on common malware infections in Dhaka. ### Protect Against Power Surges Voltage fluctuations damage network equipment and create security gaps when devices restart with corrupted configurations. Use [surge protection and UPS systems](/blog/load-shedding-computer-protection-dhaka-guide-2026) for all networking gear. ### Train Your Team Human error causes most security breaches. Conduct quarterly security awareness training covering phishing recognition, safe browsing habits, and reporting procedures for suspicious activity. --- ## When to Call BAYAS for Office Network Security Book a consultation if any of the following apply to your office: - You have experienced a security breach, malware infection, or ransomware attack in the past year - Your office WiFi is accessible to anyone walking past your storefront - You do not know what devices are connected to your network - Employees access confidential files from home without VPN - Your CCTV cameras are visible on your public network - You are setting up a new office and want security built in from day one - You need to comply with data protection requirements for clients or regulators Our [emergency computer repair service](/blog/emergency-computer-repair-dhaka) covers network security incidents as well as hardware failures — same-day response, no appointment needed. --- ## Frequently Asked Questions ### How much does office network security setup cost in Dhaka?
