In today's digital world, security oversight is not a luxury, it is an absolute necessity. Whether you are a company, a public institution or an individual concerned about your data, it is essential to know what cybersecurity tools to use to detect, analyze and counter threats. But between traditional solutions, new generation software and integrated cloud platforms, it's hard to make an informed choice without seeing it more clearly.

Why is security surveillance crucial?

Imagine a computer system like a house. Firewalls are doors, antivirus are locks, but the safety monitoringIt's the 24-hour alarm system. She warns you as soon as a suspicious behavior is detected: an unusual connection, a modified file without permission, an unknown program that runs...

Without surveillance, you're blind. And in cybersecurity, what you don't see can literally destroy you.

Top monitoring tools to know in 2025

Here are some of the essential tools to effectively secure your systems:

🔍 SIEM (Security Information and Event Management)

• Examples: Splunk, IBM QRadar, LogRhythm
• Function: aggregates the logs of all your systems, analyzes events in real time, alerts in case of anomaly.
• Why is it useful: it centralizes all security information, and helps identify attacks before they cause damage.

🧠 SOAR (Security Orchestration, Automation, and Response)

• Examples: Palo Alto Cortex XSOAR, IBM Resilient
• Function: automates response to incidents.
• Major asset: you save crazy time, and you can answer even without a big cybersecurity team.

🧮 Network Detection and Response (NDR)

• Examples: Darktrace, Vectra AI
• Function: Monitors network behaviors in real time, detects anomalies via IA.
• Strong point: very effective against ransomware or internal attacks.

🖥️ EDR (Endpoint Detection and Response)

• Examples: CrowdStrike Falcon, SentinelOne
• Function: Monitors computers, phones, servers... everything that connects.
• Essential if you have employees on telework or travel.

☁️ CSPM (Cloud Security Posture Management)

• Examples: Wiz, Prisma Cloud
• Function: Monitors the configuration of cloud environments (AWS, Azure, Google Cloud).
• Why is it essential: 90% of security errors in the cloud come from bad human configurations.

How to choose the right tools?

The choice depends on your Size, your Human Resources, and especially of your level of maturity in cybersecurity. Here are some practical tips:

• For SMEs Start with a good antivirus/EDR and simple cloud SIEM like Splunk Light.
• For large companies : integrate an SIEM, a SOAR, and an NDR with IA.
• For schools, hospitals or town halls : focus on simplicity and visibility. A good BDU and cloud solution with alerts can be enough.
• For freelancers in cybersecurity Free trial versions of SentinelOne, CrowdStrike or even OpenEDR.

Perfect, thanks for the confirmation. I shall now continue with the next sections of the article, starting from point 6 to 10 of our original plan. Here's the rest:

Human Errors: Weak but Correctable Maid

Just one click. An open attachment, a reused password, a malicious link on an email... And the ransomware is here. In cybersecurity, Human error is responsible for more than 85% of incidentsAccording to the latest reports from 2025.

Why is human being the main target?

Because it is predictable, distracted, and often untrained. The pirates know that very well. This is why they invest so much in phishing, speech-phishing or fraudulent calls. They create fake, professionally-looking emails, mimic internal messages, or pretend to be official partners. And it works.

Some recurrent examples:

• An employee receives an urgent email from his "PDG" requesting a transfer of sensitive files.
• An agent opens a PDF invoice... which contains a malicious executable.
• A technician connects an unsecured USB drive found "by chance" in front of the entrance.

The worst is that these mistakes are often made. without bad intent. But the consequences can be catastrophic.

How to correct this weak link?

1. Continuous training No single annual training. We need regular reminders, interactive sessions, short videos.
2. Simulate attacks : Simulated phishing tests are very effective in measuring vigilance.
3. Strengthening cyber culture : It's not just about technique. We need to changing behaviour. Creating a climate where to report a doubt is valued, not sanctioned.
4. Simplify the rules : Too complex policies are never respected. Prefer simple, visual, easy to remember guidelines.

In 2025, a company that does not train its teams in cybersecurity, it is like a car launched at full speed without brakes.

Artificial Intelligence at the Defence Service

Fortunately, technology is also evolving in the right direction. If hackers exploit AI to circumvent protections, companies can do the same for anticipate and neutralize them faster.

Applications of AI in cybersecurity

• Behavioural detection : The AI can learn what normal behavior is on a network. And as soon as a file acts abnormally, the alert falls.
• Prediction of attack : Some tools use machine learning algorithms to detect the warning signs of an attack.
• Automation of response The IA can isolate an infected machine, reset compromised passwords, or block suspicious IP addresses.
• Real-time threat analysis IA-enriched threat intelligence platforms cross billions of signals to identify emerging threats.

Examples of tools using AI

• Darktrace : pioneer of behavioral AI for networks.
• CrowdStrike Falcon Proactive detection of anomalies.
• Microsoft Defender for Endpoint : integrated into the Windows ecosystem with native AI.
• Wiz : Analyzes IA cloud configurations to clear faults.

Limits to be monitored

It's not magic. It can generate false positives or be manipulated so poorly trained. And above all, she does not replace humans. She's sitting there. This is why the combination of experienced analysts and tools with AI is now the norm.

The Trades of Cybersecurity: Opportunity for the Future

Faced with this permanent digital war, companies thirst for cybersecurity skills. And it feels on the labour market.

Searched profiles in 2025

1. Cybersecurity Analyst He monitors, detects, alerts.
2. Cybersecurity Engineer He designs security systems.
3. Security consultant : he audits, advises, trains.
4. Responsible for compliance GDPR/NIS2 : essential in the public sector.
5. Pen-tester / Ethical Hacker It simulates attacks to test defenses.

And there is room for everyone: beginners, students, converts, self-taught...

Where to train?

• Certifications : Google Cybersecurity Professional Certificate CEH, CPENT Gold CISSP.
• Universities and schools online : WGU Cybersecurity, OpenClassrooms, Racera.
• Bootcamps intensive The Wagon, Simplon, Ironhack.
• Internships and internships : to search on zryly.com or LinkedIn.

Wages? Very attractive.

Without forgetting that the jobs in telework It's exploding. You can work for a firm in Paris, Berlin or New York... from your living room.

Targeted Attacks on Critical Infrastructure

Hospitals, power plants, communities... have become prime targets for cyber criminals. And because: A breakdown there has an immediate and serious impact.

Why are these targets vulnerable?

• Obsolete or poorly secured systems.
• Low IT budget.
• Dependence on continuous availability.
• Personnel with little training.

In 2023, French hospitals had to transfer their patients after an attack. Town halls were unable to issue birth certificates. And even water production lines have been blocked. In 2025, these attacks increased.

How better to protect them?

• Modernize infrastructure (secure cloud passage, segmented networks).
• Reviewing cyber governance: appoint an IRS, train elected officials, allocate a real budget.
• Raise awareness of risks among all services (accommodation, secretariat, technical).
• Simulate cybercrises once a year.

Error to Avoid: Pay the Rançon

Paying is encouraging. It's financing the next attacks. And that's take the risk of never recovering your data.

The authorities formally advise against any payment. But sometimes the pressure is huge.

Why avoid paying?

• There is no guarantee that you will recover your files.
• You feed the criminal business.
• You become an "easy target" for other attacks.

Alternatives?

• Restore via your backups (hence their importance!)
• Use recovery experts.
• Report the attack to local authorities (in France: ANSSI, cyber police, CNIL).
• Mobilize your cyber insurance if you have one.
