Three Pillar
Why Your Security Strategy Needs All Three Pillars
13 October 2025 · 0x1m3 · 5 min read
Every South African business owner understands the need for security. The problem is that most only invest in one piece of it. They install endpoint protection, tick the box, and assume the job is done. It is not. A protect detect recover security strategy demands all three capabilities working together. Without that, you are building a fortress with a missing wall.
The One-Pillar Trap
Here is what typically happens. A business invests in a solid antivirus or endpoint detection and response (EDR) solution. The IT team feels confident. Threats will be caught at the door.
Then ransomware arrives through a phishing email on a Tuesday afternoon.
The endpoint protection catches it — on one machine. But the attacker has been inside the network for two weeks already. They have moved laterally across file servers, exfiltrated client data, and planted encryption payloads on twelve endpoints. The EDR flags the first detonation, but by then the damage is already spreading.
Now two questions arise that endpoint protection alone cannot answer:
- Who was watching the network? Without 24/7 monitoring and automated alerting, no one noticed the unusual login patterns, the privilege escalation, or the data transfers that preceded the attack. - Where is the backup? Without immutable, cloud-based backups, the encrypted data is gone. The business faces a ransom demand, a regulatory headache, and days of downtime.
This is not a hypothetical. It is a pattern that plays out across South African organisations every month.
Three Pillars, One Defence
OAS's Three Pillar methodology structures cybersecurity around three essential capabilities: Protect, Detect, Recover. Each pillar addresses a different phase of the threat lifecycle. Together, they create a defence-in-depth strategy that no single product can deliver alone.
Protect — Stop Threats Before They Execute
The first pillar uses SentinelOne's behavioural AI to identify and neutralise threats in real time. Unlike traditional antivirus that relies on known signatures, SentinelOne analyses how processes behave. It catches zero-day exploits, fileless attacks, and novel ransomware variants automatically.
When a threat is detected, SentinelOne responds in seconds — killing malicious processes, quarantining infected files, and rolling back encrypted data to its pre-attack state. No human intervention required.
Detect — See Everything, Respond Faster
The second pillar deploys N-able N-central for 24/7 remote monitoring and management (RMM) across every endpoint, server, and network device. Automated patch management closes vulnerabilities across 100+ third-party applications before attackers can exploit them. Anomaly detection flags suspicious activity the moment it appears.
Detection turns reactive IT into proactive security. It is the difference between discovering a breach six months later and stopping it on day one.
Recover — Restore Everything, Pay Nothing
The third pillar ensures that even in the worst case, your data comes back. Cove Data Protection delivers cloud-first, immutable backups encrypted with AES-256. Ransomware cannot reach them. Cove's TrueDelta technology produces incremental backups up to 60x smaller than traditional solutions, enabling more frequent restore points and faster recovery.
Microsoft 365 data — often assumed to be backed up by Microsoft — is protected with Exchange backups six times daily and SharePoint four times daily.
What Goes Wrong Without All Three
Consider these real-world failure patterns:
Protection without detection: The endpoint catches known threats, but no one monitors for lateral movement or unusual network behaviour. Attackers dwell undetected for weeks.
Detection without recovery: Your monitoring flags a breach within hours. Excellent. But the encrypted files cannot be restored because backups were stored on the same network — and the attacker encrypted those too.
Protection and detection without recovery: The rarest gap, but the most devastating when it matters. The breach is contained. The threat is neutralised. But corrupted data cannot be rolled back, and the last clean backup is three weeks old.
Each missing pillar creates a gap that attackers will find and exploit.
One Partner, One Console, One Strategy
What makes OAS's approach different is integration. SentinelOne, N-able, and Cove all operate from a unified N-central console. OAS manages all three pillars as a single service — no finger-pointing between vendors, no gaps between tools, no coordination delays during an incident.
OAS has delivered enterprise-grade IT solutions in South Africa for over 40 years. The Three Pillar methodology brings that proven track record to cybersecurity — structured, managed, and comprehensive.
The service is delivered as a simple per-endpoint monthly subscription. No capital expenditure. No complex licensing. One price for complete protection.
Is Your Strategy Complete?
Ask yourself three questions:
1. If ransomware hits your busiest endpoint right now, does your protection respond autonomously — in seconds, not hours? 2. Is every endpoint, server, and network device monitored 24/7 with automated alerting? 3. Can you restore your critical data — including Microsoft 365 — from an immutable backup within hours?
If any answer is "no," you have a gap. And gaps are where breaches happen.
