Most organisations can see what tries to enter their network.
Almost none can see what is already moving inside it.
Attackers live on your network for months.
Your firewall never sees them.
Once an attacker is inside — through a phishing email, a stolen credential or a compromised vendor — they move freely through your environment using the same tools and protocols your IT team uses every day. Without network monitoring, you will not know until the damage is done.
Attackers hide for months using legitimate tools
The most sophisticated threat actors do not use malware that triggers alerts. They use your own administrative tools: PowerShell, WMI, RDP, PsExec and SMB. From a firewall perspective their activity is completely indistinguishable from legitimate IT operations. Network security monitoring detects the behavioural anomalies — the unusual time of access, the unexpected data volume, the connection to an internal system this account has never touched before.
Most malware uses DNS — the most monitored protocol
Command-and-control communications, data exfiltration via DNS tunnelling and malware callbacks all exploit DNS because it is universally allowed through firewalls. Octa1ne monitors every DNS query against global threat intelligence, detects domain generation algorithm activity, identifies DNS tunnelling through query entropy analysis and blocks malicious domains before connections are established — eliminating the most common C2 channel attackers rely on.
Lateral movement is where all serious damage begins
When an attacker breaches your perimeter, their immediate objective is to move laterally to reach their true target. This is where credentials are escalated, domain controllers are compromised and ransomware staging begins. Network monitoring is the most reliable detection layer for lateral movement — identifying the specific traffic patterns of pass-the-hash attacks, Kerberos ticket abuse, unusual internal scanning and mass SMB connections that precede a major incident.
AI-powered network detection.
No vendor lock-in.
We select and operate the network security tools that fit your environment — whether you run on-premises infrastructure, a cloud-first stack or a hybrid mix. We do not force a single vendor. We deploy what delivers the best detection for your specific network.
If you have already invested in Darktrace, Vectra, Palo Alto or another network detection platform, we can take over 24/7 monitoring and management rather than replacing your investment. Most clients see time-to-value in days, not months.
Talk to us about your existing tools →Uses unsupervised machine learning to model normal behaviour across your entire network and identify subtle deviations in real time — including zero-day attacks and insider threats that signature-based tools miss entirely.
Correlates network, identity and cloud signals to surface the highest-priority threats. Exceptional at detecting lateral movement, privilege escalation and attacker behaviour inside your network after initial access.
Combines network, endpoint and cloud telemetry in a single platform. Best-in-class for organisations that want unified detection across their full environment from one vendor trusted by global enterprises.
Native Azure network monitoring, flow log analysis and cloud workload protection. The go-to for Microsoft Azure environments with native integration into Sentinel and no additional data egress costs.
DNS filtering, malicious domain blocking, web gateway security and DDoS protection at the network perimeter. Blocks threats before connections are established using continuously updated global threat intelligence.
Industry-standard open-source network analysis frameworks used by security teams worldwide. We deploy and manage these for clients where flexibility and cost-efficiency are priorities alongside commercial tools.
Six network attack techniques
used against organisations every day
Automated Reconnaissance
Threat actors continuously scan every public IP every few hours using tools like Shodan and Censys, probing for exposed services, default credentials and unpatched vulnerabilities. Octa1ne correlates inbound scanning activity with subsequent attack attempts to identify targeted campaigns before they succeed.
Pass-the-Hash and Kerberos Attacks
Stolen NTLM hashes and Kerberos tickets allow attackers to authenticate to network resources without knowing the actual password. These attacks generate specific detectable patterns in authentication traffic that Darktrace, Vectra and Microsoft Defender for Identity identify in real time.
DNS Tunnelling and Covert Exfiltration
Sophisticated attackers encode stolen data inside DNS queries — a protocol almost universally allowed through firewalls. Thousands of queries per hour can exfiltrate entire databases. Octa1ne monitors DNS query volumes, patterns and entropy to identify tunnelling automatically across all your environments.
Living-off-the-Land Lateral Movement
Attackers using built-in Windows tools — WinRM, WMI, PsExec, Remote Registry — generate network traffic identical to legitimate admin activity unless you have deep behavioural baselines. Darktrace and Vectra AI establish your specific normal behaviour and surface the subtle deviations these attacks create.
Ransomware Network Propagation
Enterprise ransomware spreads at machine speed using SMB exploits, admin shares and compromised credentials. Octa1ne detects the characteristic patterns of ransomware propagation — mass internal connection attempts, rapid file access across network shares — and triggers automated device isolation before encryption completes.
Cloud-to-On-Premises Attack Paths
Attackers who compromise cloud workloads pivot to on-premises infrastructure through hybrid connectivity. These cross-environment attack paths are invisible if you monitor cloud and on-premises separately. Octa1ne provides unified monitoring across both environments, detecting the pivoting behaviour attackers rely on.
Full network visibility deployed
fast, smooth and zero disruption
We map your entire network — perimeter devices, internal segments, cloud environments, remote access and hybrid connectivity. Existing tools are assessed. Data sources identified. Monitoring strategy agreed based on your specific architecture and risk priorities.
Network monitoring sensors deployed or configured across your environment. Flow data collection from firewalls, switches and cloud gateways activated. Darktrace, Vectra or your chosen tool connected to all data sources. DNS security configured and validated.
Two days of live telemetry used to establish accurate behavioural baselines across users, systems and applications. Detection thresholds tuned to eliminate false positives from legitimate business activity. Custom detection rules written for your environment.
Response playbooks tested and validated: malicious IP blocking, DNS blocking, device quarantine. Alert workflows confirmed with your team. Escalation paths agreed. Everything validated against simulated threat scenarios before going live.
Full network monitoring live. Network asset inventory delivered. Initial network security posture findings presented. Your dedicated engineer walks through what is monitored, what alerts look like and the response process. Protection is active from this moment.
Network monitoring collects flow data and telemetry from your existing infrastructure — firewalls, switches and cloud gateways — without placing anything inline with your traffic. Your network performance is completely unaffected. Your users notice nothing.
