Defend every layer.
Trust nothing.
Verify everything.
Modern threats don't knock — they walk through gaps your team didn't know existed. Onel designs and implements layered security across your network, systems, applications, cloud, and data — so when an attack comes, your business keeps running.
Network & Perimeter Security
NGFW, SD-WAN security, cloud firewalls, and network segmentation
Email & Collaboration Security
Anti-phishing, Safe Links, DMARC, and mail gateway protection
Web Application Firewall
WAF protecting web apps from OWASP Top 10 and DDoS attacks
Microsegmentation
Zero Trust network segmentation — limit lateral movement
DLP & Data Security
Prevent sensitive data leaving — Purview, Defender, and DLP policies
SIEM & Threat Detection
Microsoft Sentinel — visibility and response across your entire environment
Secure the perimeter. Control what comes in and out.
Your network perimeter is the first line of defence. Onel designs and deploys next-generation firewall architectures that inspect all traffic — not just at the edge, but between internal zones — so threats can't move freely once inside.
Next-Generation Firewall (NGFW)
Cloud Firewall & SASE
Stop attackers from moving through your network freely.
A flat network is an attacker's best friend — one compromised device can reach everything. Microsegmentation divides your network into isolated zones with enforced access controls between them. Even if an attacker gets in, they can't go anywhere.
Segmentation Architecture
East-West Traffic Security
Protect your web applications from the attacks targeting them daily.
Web applications are the most attacked surface in most organisations — exposed to the public internet, often storing sensitive data, and directly accessible to unauthenticated users. A WAF sits in front of your applications and blocks attacks before they reach your code.
Azure WAF / Application Gateway
Palo Alto Prisma & Fortinet WAF
Email is the number one attack vector. Treat it that way.
Over 90% of cyberattacks start with an email. Phishing, spear-phishing, business email compromise, and malicious attachments are constant threats. Onel implements layered email security that blocks attacks before they reach your users' inboxes.
Defender for Office 365 (Plan 2)
DMARC / DKIM / SPF + Email Auth
Know where your sensitive data is. Control where it goes.
Data breaches don't always come from external attackers — sometimes it's an employee accidentally emailing a customer list, or sharing a file containing health records to a personal account. DLP policies automatically detect and block sensitive data from leaving your organisation through any channel.
Microsoft Purview DLP
Information Protection & Classification
Protect every device. Detect every threat. Respond fast.
Endpoints are the most common initial access point for attackers. Modern endpoint protection goes far beyond antivirus — it detects suspicious behaviour, investigates the full attack chain, and responds automatically to contain threats before they spread.
Microsoft Defender for Endpoint (MDE)
Privileged Access & Application Control
See everything. Respond before it becomes a breach.
Individual security tools generate alerts in isolation. A SIEM correlates signals from across your entire environment — network, endpoints, identity, email, and cloud — to surface real threats and give your team the context to respond fast and effectively.
Microsoft Sentinel SIEM
Threat Intelligence & Hunting
Zero Trust — the architecture that ties it all together.
Zero Trust is not a product — it is an architecture principle. Onel designs all security engagements around Zero Trust: verify explicitly, use least privilege access, and always assume breach.
Identity
Every access request is authenticated and authorised — MFA, Conditional Access, and PIM for all users and admins.
Endpoints
Only compliant, managed devices gain access — posture checked at every connection attempt via Intune and MDE.
Network
Segmented, policy-enforced network — least-privilege access between zones, encrypted traffic, no implicit trust.
Applications
Applications protected by WAF, API security, and access proxies — never exposed directly to the internet.
Data
Sensitive data classified, labelled, encrypted, and governed — DLP prevents exfiltration across every channel.
Across all five pillars, Microsoft Sentinel and Defender XDR provide unified visibility — correlating signals from identity, endpoints, network, applications, and data into a single security operations platform. Onel can deploy, configure, tune, and operate this platform as a fully managed security service — giving your organisation enterprise-grade security operations without building an in-house SOC.
Security built to meet your compliance obligations.
Onel's security engagements are designed to support your compliance requirements — not just your technical security posture. Every control we implement is mapped to the relevant framework.
