Altospam, your partner for Microsoft 365 email security

Microsoft 365 is the main target platform for phishing attacks

Microsoft 365 is the most widely used suite in the world. The ever-increasing adoption of Microsoft 365 by organizations makes it a prime target for hackers. With nearly 300 million M365 users, hackers continue to develop new techniques to target this ever-growing number of users. M365 therefore represents an opportunity for hackers to gain access to a wealth of data. While Microsoft’s native email security is capable of intercepting standard threats, it is powerless against the dynamic and sophisticated attacks now targeting Microsoft 365.

By 2020, 85% of Microsoft customers have experienced a breach of their email. To improve your security against unknown and constantly evolving threats, we recommend that you complement your existing Microsoft 365 security mechanisms. Reinforce your Microsoft 365 email security with an additional layer against sophisticated attacks: anti-phishing, anti-spear phishing (against Business Email Compromise (BEC)), identity theft, anti-ransomware protection to effectively protect your business and your users.

Why is it necessary to reinforce Microsoft 365’s native antispam with Altospam?

Compatible Microsoft 365

Attacks on Microsoft are lucrative. Choose productivity AND security. To enjoy the benefits of Microsoft without increasing the risk of cyber attacks, it’s essential to complement and strengthen M365 with our cloud-based solutions. This not only increases protection at the email level, but also ensures business continuity and data protection in the event of a service interruption, thanks to our DRP service.

Microsoft 365’s native email security is capable of intercepting standard threats, it is powerless against dynamic attacks. Sophisticated email attacks, such as phishing, ransomware and zero-day attacks, can easily bypass Microsoft’s security defenses. Altospam’s Mailsafe uses AI algorithms to meticulously analyze the content and context of emails. Our solution is capable of blocking the most dynamic and sophisticated ransomware, phishing and spear phishing attacks, as well as non-priority advertising mail (including anti-advertising otpion).

Protect your employees and your M365 work environment.

Even with Microsoft Defender in place, hackers can bypass native anti-spam and operate inside an e-mail network, using compromised accounts or social engineering to send malicious e-mails internally or externally. Your employees are also likely to open attachments, click on links… With Mailout, we prevent the propagation of attacks internally or towards a customer or partner.

Your most frequently asked questions about email security with M365

  • Why is Microsoft 365 the platform most attacked by hackers?

    Microsoft 365 est l’une des plateformes les plus attaqu茅es par les hackers en raison de sa popularit茅 et de son utilisation r茅pandue dans les entreprises. Avec plus de 300 millions d’utilisateurs actifs mensuels, Microsoft 365 repr茅sente une cible attrayante pour les cybercriminels cherchant 脿 acc茅der 脿 des informations confidentielles, 脿 des identifiants de connexion ou 脿 des informations financi猫res. De plus, Microsoft 365 est une plateforme tr猫s complexe avec de nombreux services interconnect茅s, ce qui rend la s茅curisation de l’ensemble du syst猫me particuli猫rement difficile et n茅cessite des comp茅tences et une expertise en s茅curit茅 informatique. En outre, certaines entreprises peuvent ne pas avoir pris toutes les mesures de s茅curit茅 n茅cessaires pour prot茅ger correctement leur environnement Microsoft 365, ce qui les rend encore plus vuln茅rables aux attaques.

  • How to avoid phishing attacks on Microsoft Office 365?

    Voici quelques mesures pour 茅viter les attaques de phishing sur Microsoft 365 :

    • Sensibiliser les employ茅s : Les utilisateurs doivent 锚tre form茅s 脿 identifier les signes d’un email de phishing. Ils doivent 锚tre encourag茅s 脿 ne jamais cliquer sur les liens ou les pi猫ces jointes suspects, m锚me s’ils semblent provenir d’une source fiable.
    • Utiliser une solution de s茅curit茅 compl猫te : les entreprises doivent envisager de mettre en place une solution de s茅curit茅 compl猫te pour M365, telle que Mailsafe d鈥橝ltospam, qui peut bloquer les emails de phishing avant qu’ils n’atteignent les bo卯tes de r茅ception des utilisateurs.
    • Activer l’authentification 脿 deux facteurs (2FA) : L’activation de l’authentification 脿 deux facteurs peut aider 脿 emp锚cher les attaques de phishing, car les utilisateurs doivent fournir une deuxi猫me forme d’identification, comme un code de s茅curit茅, avant de pouvoir acc茅der 脿 leur compte.
    • Mettre 脿 jour r茅guli猫rement les logiciels : Les entreprises doivent s’assurer que tous les logiciels et applications utilis茅s sur leurs ordinateurs sont 脿 jour, car les hackers exploitent souvent les vuln茅rabilit茅s des logiciels obsol猫tes pour mener leurs attaques.
  • Why install an extra layer of email protection with Microsoft 365?
