Introduction
In a context where cybersecurity represents a strategic issue for companies of all sizes, the threat of phishing remains one of the most widespread and feared attack vectors. At IT INNOVE, we daily support organizations concerned with protecting their digital assets against these growing risks. Thanks to our expertise in developing secure digital solutions and our constant monitoring of the evolution of cyber threats, we place IT security at the heart of our innovation approach. This article offers you a technical and accessible dive into the definition of phishing, its mechanisms, its impacts on your business, and the best practices for protecting against it sustainably.
Phishing: definition and types of attacks
Phishing, or fishing in French, refers to all fraudulent techniques aimed at deceiving a user in order to extract sensitive information (identifiers, passwords, banking data) or to incite them to perform a malicious action. According to ANSSI, phishing accounts for over 70% of the attempted compromises observed in businesses source ANSSI.
The types of phishing are multiple:
- Email phishing: The attacker impersonates a trusted third party to send an email containing a fraudulent link or attachment.
- Spear phishing: Personalized targeting of an employee or specific service, often after a phase of information gathering (reconnaissance).
- Vishing and smishing: Respectively by phone (voice) or SMS, these variants aim to obtain information or trigger an action (transfer, session opening).
- Pharming: Redirecting traffic to a fake site imitating a legitimate portal to steal login credentials.
Understanding the diversity of these attacks is crucial to anticipate and adapt your defense strategy to the constantly evolving threats.
Why does phishing target businesses?
Phishing remains a preferred weapon for cybercriminals to target businesses because it exploits the human factor – often the most vulnerable link. IT decision-makers and security managers face multiple challenges: volume of exchanged emails, multiplicity of remote accesses, increased sharing of sensitive information. According to the latest report from CESIN, nearly one in two companies has been the victim of a phishing attempt at least once in the past 12 months.
The consequences can be considerable:
- Compromise of business accounts (access to internal tools, data leaks)
- Activity blockage (ransomware attack following a click on a trapped attachment)
- Damage to reputation (public disclosure of sensitive information)
For IT INNOVE, it is not just about putting in place technological barriers, but about building a culture of digital vigilance across the organization.
Steps of a phishing attack: decoding
Phishing attacks always follow a proven pattern:
- Preparation: The attacker collects information about their target (structure, organization chart, habits).
- Impersonation: Creation of an email or fake site imitating a trusted interlocutor (bank, partner, general management).
- Incitement: Request for urgent action (payment, login, document opening).
- Exploitation: Recovery of entered data or installation of malicious software.
A recent testimony from one of our clients in the financial sector illustrates the importance of anticipation:
"We recently thwarted a spear phishing campaign thanks to the awareness training provided by IT INNOVE. Identifying a suspicious message helped avoid the compromise of several strategic accounts."
It is by understanding these steps that one can effectively train their teams and implement appropriate controls.
Best practices to protect your business from phishing
The fight against phishing requires a comprehensive approach combining tools, processes, and training. At IT INNOVE, we systematically recommend an action plan structured around four axes:
1. Securing digital tools
Implementing a strong authentication solution (MFA), activating anti-spam filters, and relying on secure hosting, as proposed by our professional hosting offer, are essential measures.
2. Awareness and training of employees
Offering regular training sessions on phishing and using simulation campaigns to reinforce vigilance on a daily basis. Feedback from our clients shows that pedagogy remains the most effective weapon:
"The workshops organized by IT INNOVE allowed us to reduce phishing-related incidents by 60% in less than a year."
3. Incident management and rapid response
Establishing a clear procedure for reporting a suspicious email, isolating a compromised machine, and notifying the hierarchical chain. IT INNOVE supports its clients in drafting these protocols and ensures responsive support in case of emergency (see our maintenance and support offer).
4. Audit and continuous improvement
Regularly conducting security audits to evaluate the effectiveness of existing measures and adjust internal policies. An external audit by an expert provider can detect often unsuspected vulnerabilities.

Current trends in phishing and how to anticipate tomorrow
Phishing attacks are evolving rapidly: artificial intelligence generating more credible emails, voice impersonation, and the multiplication of channels (social networks, collaborative platforms). According to the Verizon Data Breach Investigations Report 2024, phishing remains the main entry point for over 50% of documented compromises. Furthermore, according to the Digital and Innovation Observatory, by 2026, 62.5% of software development companies plan to invest in artificial intelligence to improve their IT services.
In light of this sophistication, agility and innovation remain key:
- Strengthening monitoring of new operating modes
- Regularly testing your devices through simulated attacks
- Collaborating with expert partners for evolving protection
At IT INNOVE, we constantly invest in R&D and the continuous improvement of our solutions to ensure our clients a digital environment that is always safer, without hindering growth.
