AI has changed the game — on both sides
In 2025, AI-powered cyberattacks reached a new level. What took a human attacker weeks of preparation can now be done in hours through automation:
- Hyper-personalised phishing — AI analyses the target's social media and writes an email indistinguishable from a real professional message
- DeepfakesAI-generated synthetic content — Voice, face or video imitating a real person, used to deceive a colleague (e.g.: fake CEO call ordering a wire transfer). voice — a call imitating the CEO's voice to order a wire transfer
- Automatic malware generation — unique variants created on the fly, invisible to traditional antivirus
- Intelligent brute-force attacks — AI tests the most likely combinations first
The question is no longer whether your business will be attacked — but when. And the follow-up: will you be able to detect, respond and recover?
Defensive AI: how it works
Defensive AI turns the same technologies against the attackers. Where a traditional antivirus compares known signatures (reactive), AI learns the normal behaviour of your IS and detects anomalies in real time (proactive).
Behavioural detection (EDR/XDREndpoint Detection & Response / Extended Detection & Response — Advanced detection and response on your workstations and network, powered by AI.)
AI monitors every workstation, every network flow. An employee downloading an unusual file at 3am? A process encrypting files en masse? AI sees it before the damage is done — and isolates the threat automatically.
Weak signal correlation (SOCSecurity Operations Center — 24/7 cyber monitoring centre that detects and handles incidents continuously.)
A failed password here, a VPN connection from an unusual country there, a suspicious email earlier in the day — taken individually, nothing alarming. The SOC's AI correlates these weak signals and identifies an ongoing attack scenario, well before a human would make the connection.
Predictive infrastructure monitoring
AI isn't just for security. It also detects infrastructure anomalies — a disk filling abnormally fast, a network link with increasing latency, a server consuming CPU for no reason. We intervene before the failure, not after.
AI-augmented reporting and QBR
Executive summaries (monthly reports, QBRQuarterly Business Review — Revue trimestrielle de l'activité IT avec le dirigeant. quarterly reviews) are generated by AI and reviewed by your vDSIDSI à temps partagé — Un Directeur des Systèmes d'Information externalisé.. Result: clear, visual, decision-oriented reports — not a 40-page PDF that no one reads.
The trap: AI without governance
AI is a powerful tool — but without a framework, it becomes a risk:
- Your employees use ChatGPT on the sly, without a data policy — your clients' confidential information ends up in a third-party model
- AI tools are integrated without security validation — vulnerabilities are introduced without anyone knowing
- No AI usage policy exists — everyone does what they want
AI without governance is like a Swiss Army knife left open in a pocket: it can be useful, but it can also cut in the wrong place.
How TIPTOP integrates AI — in practice
AI at TIPTOP, at every level of the model:
- Infrastructure — predictive monitoring, network anomaly detection, failure anticipation
- Cybersécurité — augmented EDR/XDR, SOC correlation, automatic alert qualification, AI anti-phishing
- Gouvernance — augmented executive reporting, QBR summaries generated and reviewed by the vCIO
- Métier — AI data governance framework, usage policy, team training
The level of AI integration depends on your TOTALPro or CyberPILOT plan. Contact us to learn more.
For 2 years, AI has been amplifying our teams' work — monitoring, protecting, governing — enabling us to fight increasingly powerful AI-driven attacks on equal footing. We stay one step ahead.
