Layered Security That Covers Every Attack Surface

Modern businesses face threats from every direction — malware, ransomware, phishing, insider threats, and unpatched vulnerabilities. ATOM IT SERVICES takes a layered approach to security: protecting your perimeter, your network, your endpoints, and your data all at once.

Firewall Setup & Management

Hardware Firewall Deployment
Installation and configuration of pfSense, Fortinet FortiGate, Cisco ASA, SonicWall, and other enterprise firewalls at your network perimeter.
Firewall Rules & Policies
Custom inbound and outbound rule configuration to whitelist only the traffic your business needs and block everything else by default.
NAT & Port Forwarding
Secure network address translation and port forwarding setup for servers, cameras, VoIP, and remote access — properly secured and documented.
Content Filtering & Web Blocking
Block harmful, inappropriate, or productivity-sapping websites at the network level — keeping employees productive and systems safe.
Firewall AMC & Monitoring
Annual maintenance with rule reviews, firmware updates, log analysis, and 24/7 alerts for firewall breach attempts or policy violations.

Network Security

Intrusion Detection & Prevention (IDS/IPS)
Snort-based and commercial IDS/IPS deployment to detect and automatically block suspicious traffic patterns and known attack signatures.
Network Security Audit
Comprehensive assessment of your network infrastructure, identifying open ports, misconfigured devices, weak passwords, and policy gaps.
Network Segmentation
VLAN-based network segmentation to isolate sensitive systems — servers, point-of-sale, CCTV, guest WiFi — from each other.

Endpoint Security

Antivirus & Anti-Malware Deployment
Centralised deployment of enterprise antivirus solutions (ESET, Kaspersky, Microsoft Defender) across all desktops, laptops, and servers.
Patch Management
Automated OS and application patch management to close known vulnerabilities before attackers can exploit them.
USB & Device Control
Policies to prevent unauthorised USB drives and external devices from connecting to your network — a common ransomware entry point.

Data Security & Backup

Data Encryption
Full-disk encryption (BitLocker, VeraCrypt) and file-level encryption to protect data at rest on servers, desktops, and laptops.
Disaster Recovery & Backup
Automated local and offsite backups with tested restore procedures — so ransomware or hardware failure never brings your business to a halt.
Vulnerability Assessment
Periodic scanning of your systems and websites with professional tools to find and remediate weaknesses before they're exploited.
Threats We Protect Against

Modern Cyber Threats Require Modern Defence

The threat landscape in India is evolving rapidly. These are the most common attacks we protect Delhi businesses from every day.

Ransomware
Malware that encrypts your files and demands payment. We prevent entry, detect spread, and ensure backups are in place for recovery.
Phishing Attacks
Fake emails that steal credentials. We deploy email filters, DNS protection, and train your staff to spot social engineering attempts.
Unauthorised Access
Brute-force attacks on RDP, SSH, and admin panels. We enforce strong authentication, rate limits, and access control policies.
WiFi Eavesdropping
Attackers intercepting data on poorly secured wireless networks. We enforce WPA3, VLAN isolation, and rogue AP detection.
Data Theft
Internal and external data exfiltration. We implement DLP policies, USB controls, encryption, and audit logging to prevent leaks.
Unpatched Vulnerabilities
Known software flaws exploited before you patch them. Our patch management keeps every system current and protected.
