Protection of corporate network, IDS/IPS system and secure segmentation

We build layered defences for the corporate perimeter and prevent ransomware from spreading (Lateral Movement) within the office. We implement next-generation firewalls, NGFW (FortiGate, pfSense), deploy attack detection and active blocking systems, IDS/IPS (Suricata, CrowdSec), and securely divide the network into isolated security zones.

✓ Network micro-segmentation on isolated VLANs: full isolation of servers, accounting, and guest Wi-Fi
✓ Deep packet inspection (DPI) and detection of hidden malicious traffic in real time
✓ Automatic blocking of connections with malicious command & control servers (C2 Command & Control)
✓ Implementation of modern NGFW solutions with application control, antivirus at the gateway, and content filtering

[ DEEP NETWORK DEFENSE ]

Why a flat network ("everything in one subnet") is the main cause of business loss during attacks

In the "flat" network, the virus-encryptor from one infected computer infects database server clusters in a matter of minutes

[ 01 ]

Localization and stopping of ransomware viruses

Thanks to strict segmentation and prohibition of cross-segment traffic, even if a regular laptop picks up malicious software, it will not be able to reach critical 1C/ERP servers and backup copies.

[ 02 ]

Detection of intrusion before data theft

IDS/IPS systems detect unusual port scanning, attempts to brute-force passwords to internal services and attempts to exploit vulnerabilities of operating systems.

[ 03 ]

Monitoring of Work Internet Traffic Usage

Filtering of dangerous web categories, blocking of harmful links, torrents and anonymizers directly on the company's network gateway.

[ 04 ]

Full compliance with cybersecurity regulations

Network segmentation and the presence of IDS/IPS are mandatory requirements of international standards PCI-DSS (for card processing), ISO 27001 and cybersecurity requirements for critical infrastructure.

[ENGINEERING SCHEDULE FOR PROTECTION]

What is included in the comprehensive network security solution

Full spectrum of network firewall configuration, packet analysis systems, and filtering rule setup

[ STEP 01 ] VLAN Segmentation

Designing architecture of secure zones and VLAN microsegmentation

We divide the infrastructure into isolated segments: application servers, databases, management segment (OOB Management), office PCs and guest Wi-Fi.

[ STEP 02 ] NGFW Implementation

Implementation of next-generation firewall (NGFW) between networks

We deploy and finely configure hardware or virtual firewalls FortiGate / pfSense / OPNsense with a strict policy of "everything is forbidden unless explicitly allowed".

[ STEP 03 ] Suricata IDS/IPS

Deployment of detection and prevention system for intrusions (IDS/IPS)

We integrate the Suricata or Snort analyzer with daily updates of known exploit signatures (Emerging Threats Pro) to intercept attacks.

[ STEP 04 ] C2 Defense

Blockage of hacker C2 & DNS Sinkhole servers

We implement secure DNS filters and botnet connection blocking gateways to prevent malicious software from loading an encryption module or connecting to a curator.

[ STEP 05 ] CrowdSec Protection

Collective behavioral protection CrowdSec

Connecting intelligent agents CrowdSec, which analyze password guessing attempts and automatically block attacking IP addresses at the firewall level.

[ STEP 06 ] Testing & Map

Security rule stress-testing and documentation transfer

We conduct attack simulations to test the reaction of IDS/IPS, test isolation between subnets, and create a detailed network map.

[ FREQUENT QUESTIONS ]

Answers to common questions from customers

Key details regarding terms, independent website editing, and rights transfer.

In an unsegmented ("flat") network, each computer sees all other devices. If a regular accountant or manager accidentally opens a malicious letter with a virus, the malicious program will immediately scan the network and infect the 1C main servers, databases and network storage (NAS) without any obstacles, leading to a complete business stoppage.

IDS (Intrusion Detection System) — this is a system for detecting intrusions, which passively "listens" to a copy of traffic and only sends an alert to the admin upon detecting an attack. IPS (Intrusion Prevention System) is located directly in the traffic flow and is capable of instantly dropping malicious network connections and blocking the IP address of the attacker on the firewall within milliseconds.

Not required. If the budget is limited, we can perfectly implement a reliable enterprise-level protection based on a powerful open-source solution pfSense or OPNsense, installed on a standard server, or properly configured MikroTik RouterOS equipment with external agents CrowdSec.

No. Segmentation does not mean full isolation. We configure a firewall so that managers' computers have access to printers and databases via strictly defined ports (for example, 443 for the web panel and 9100 for printing), but any malicious network traffic or attempts to directly connect to system ports will be blocked.

Lateral Movement (Horizontal Movement) — this is a tactic used by hackers, when they use one insignificant computer as a base for attacks on the rest of the internal network nodes after gaining control over it. Thanks to port isolation (Port Isolation) and inter-segment filters, computers from the same department will even not be able to attack each other.
