It’s called Mailsafe, and it’s an outsourced online service that takes the hassle out of dealing with spam. This solution saves you from heavy and costly investments, since the fight against spam and other threats (phishing, spear phishing, ransomware, viruses…) is entrusted to professionals who guarantee the quality and availability of the service.

icône bleue Spear Phishing

Anti spear phishing

Spear phishing is one of the most targeted and personalized of all email attacks. Spear phishing or BEC (Business Email Compromise) attacks are among the most costly attacks, based on the usurpation of the sender’s identity. Our Mailsafe email security solution is designed to detect president scams (
FOVI
) and spear phishing emails.

Anti-relay

Mailsafe from Altospam fights relaying to prevent your server being used by a third party to send illicit mail.

Anti scam

The
scams
are e-mail scams in which you are solicited for large sums of money.

Bounce management

Bounces are handled in such a way that legitimate bounces (those corresponding to real distribution failures concerning you) are accepted and those originating from spam sent by spammers who have impersonated you are refused. ALTOSPAM’s action on bounces can be configured to accept or reject them.

Denial of service (DDOS)

Your servers are no longer directly visible on the Internet, but are accessible via ALTOSPAM. Mailsafe includes specific rules to prevent denial-of-service attacks.

Anti advertising

Anti-advertising filtering is a free Mailsafe option for blocking the flow of advertising mails. Commercial email, unlike spam, is legal. Activating this option allows the administrator to block the reception of advertisements for some or all of his users.

How our anti-phishing, anti-spam, anti-ransomware solution works?

Altospam’s Mailsafe is a real-time online anti-spam and anti-virus solution. This service is an outsourced gateway through which all your e-mails pass to be sorted, filtered and redirected to your servers, or refused in the event of identified e-mail or malware: phishing, spear phishing, ransomware, spam or viruses. Your mail server then receives mail as before, but without spam or viruses.

You have access to your administration console, from which you can check whether spam or viruses have been detected. You can view your reports, analysis logs and manage your black and white lists.

If your mail server is unavailable for some time, your e-mails are temporarily stored on our ALTOSPAM servers until service is restored.

Altospam’s Mailsafe combines 16 anti-spam technologies, 6 anti-viruses and other security services such as anti-replay, anti-scam, anti-phishing, anti-advertising and protection against denial-of-service attacks (Ddos). Anti-ransomware systems combined with advanced anti-spam rules guarantee a veritable fortress against all types of known and unknown malware. What’s more, this e-mail security software ensures the highest possible availability of your e-mail.

Mailsafe’s strength lies in its judicious combination of the very latest techniques for detecting spam and cyber-attack threats: RBL, heuristics, Bayesian method, spam databases, URLs, DNS registration, automatic Whitelist, as well as the very latest Greylisting and Teergrubing processes.

Unsolicited e-mails and attack threats are rejected before they even reach your mail server, so they don’t clog up your network or your employees’ mailboxes, resulting in a quantifiable improvement in network performance. What’s more, this solution is synonymous with security, as it effectively combats phishing, spear phishing, ransomware, denial of service attacks, relaying and viruses.

Altospam’s commitment to quality guarantees a low rate of false positives (legitimate messages considered as spam), which can be detrimental to your business.

Based on a standard protocol, Altospam’s Mailsafe is compatible with your mail server. Our ASP (or SaaS) software is reasonably priced for both small businesses and international groups.

How Mailsafe anti-spam and anti-virus technology works

Picto Analyse heuristique

Heuristic analysis

Heuristic analysis is a set of rules represented as regular expressions. It searches for e-mails whose headers and/or bodies correspond to very specific characteristics known to have a high probability of being spam. ALTOSPAM uses a custom rules base to identify both American and French spam.

Picto Liste noire - Liste Rouge

Blacklist | IP Reputation

RBL (Realtime Blackhole List) or DNSBL (Back List DNS) are lists of servers or networks known to assist, host, produce or retransmit spam, or provide a service that can be used as a medium for sending spam. Mailsafe uses the leading community and commercial RBLs on the market.

Picto Bases collaboratives

Collaborative spam databases

These spam signature databases are used in the same way as virus signature databases. They are fed by users of anti-spam solutions.

Picto Enregistrement DNS

DNS records

Checks the correlation between the source server’s IP address and its name via a reverse DNS query. Typically, dedicated mail servers have a fixed, bijective IP address with its associated domain name. This information can’t always be used with shared messaging services, but is still worth including in the analysis.

Picto Filtres Bayésiens

Bayesian filters

Probabilistic filtering method learning e-mails based on the statistical distribution of keywords in e-mails. This type of algorithm adapts itself based on the analysis of known spam and non-spam emails.

Picto Liste Blanche / Liste Verte

White list

List of safe sites, hosts, domains or addresses. By default, very few hosts are considered safe, as their addresses could be spoofed by spammers. However, Altospam uses a self-learning whitelist system to speed up processing time for transmitters already tested and considered safe. What’s more, Altospam lets you set up your own whitelist.

Picto Historique des transactions

Transaction history

Previous transactions between the sender and receiver of a message influence the result of the analysis. People who are used to sending each other legitimate e-mails have no reason to send each other spam.

Analyse Pièces Jointes

URL addresses

The purpose of analyzing the URLs in the message body is to identify and filter the e-mail according to the desired action: the user clicking on a promotional link. This analysis is based on the detection of suspicious sites and URLs (numeric, badly formatted).

Picto SPF et DKIM

SPF and DKIM

Anti-spam techniques known as SPF (
Sender Policy Framework
) and DKIM (
DomainKeys Identified Mail
) are designed to authenticate the sender of a message. SPF announces the mail servers authorized to send emails for a given domain. DKIM signs emails sent by mail servers to ensure their integrity.

Picto Validation du domaine émetteur

Sender domain validation

To be considered legitimate to send e-mail, a domain must comply with a certain number of standards. We analyze the email sender’s domain to validate that the sender is able to receive emails.

Picto Analyse HTML et Pdf

Image, HTML & Pdf analysis

HTML code embedded in messages, as well as certain PDF files, may contain dangerous javascript elements. Mailsafe examines the HTML code and PDF files contained in an e-mail to identify any dangerous code or abnormal behavior.

ALTOSPAM examines the images and PDF files contained in an e-mail on various bases: number, type, size, format and dimensions, then compares these criteria with the characteristics of the images used by spammers.

Teergrubing

Teergrubing

A technique for significantly reducing the response speed of the server by maintaining the session.
SMTP
, on certain connections considered suspicious. Teergrubing can be used to restrict the spam server.

Picto Greylisting

Greylisting

The greylisting is an anti-spam technique that consists of temporarily rejecting a message, by sending a temporary refusal code to the sending server. The sending server resends the mail after a few minutes – most spam servers don’t bother! (Cf.
Our article on Greylisting
)

Picto Test de Turing

Turing test

This technique, also known as challenge/response, consists of sending an email requesting authentication to the sender.
authentication request to the sender
of the message (via the reproduction of a displayed code) to ensure its actual physical existence. Used on its own, this technology has a number of disadvantages (filtering work shifted to the message sender, systematic sending of often unsolicited messages, generation of false positives). When integrated with other technologies and used judiciously at the end of the analysis, it frees up the
false positives
unresolved.

Office document control

VBA macros or scripts in Office documents are currently one of the main vectors of viral infection. Using sandboxing, Mailsafe monitors the activity of these scripts to establish their potential dangerousness, in order to identify and block dangerous attachments.

  • How long does it take to set up Altospam's Mailsafe solution? Do I need to install software?

    La solution Mailsafe d’Altospam est mise en place en quelques minutes après signature du contrat utilisateur et paiement. Sa mise en place nécessitant la modification de votre DNS, il convient de prévoir une durée de 48 heures, liée au rafraîchissement des DNS internationaux, pour être certain que tous les mails transitent bien par Mailsafe d’Altospam. Quel que soit le temps nécessaire aux rafraîchissements des DNS, tous les messages vous arriveront

  • How much spam is actually blocked by Altospam's Mailsafe?

    Le taux mesurĂ© sur notre plate-forme est actuellement de l’ordre de 98,7%. Vous pouvez considĂ©rer, suivant le risque d’exposition de votre sociĂ©tĂ© aux spams, qu’ALTOSPAM bloquera entre 99% et 100% des spams. D’autre part, Altospam  s’engage contractuellement sur la qualitĂ© de service (SLA) en garantissant un faible taux de spams et de faux positifs, ces messages lĂ©gitimes interprĂ©tĂ©s comme spams.

  • What exactly do you mean by false positives?

    Un faux-positif est un message licite interprĂ©tĂ© par une solution antispam comme Ă©tant un spam. Le taux de faux-positifs est le critère le plus important de qualification d’une solution antispam. C’est pourquoi ALTOSPAM a Ă©tĂ© pensĂ© dès sa conception de manière Ă  rĂ©duire au maximum le taux de faux-positifs.

  • Does ALTOSPAM increase the delivery time of legal e-mails?

    En règle gĂ©nĂ©rale, les messages arrivent aussi rapidement que d’habitude. Ils transitent par Mailsafe d’Altospam et sont immĂ©diatement renvoyĂ©s sur le serveur de votre entreprise. Par contre, en cas d’ambiguĂŻtĂ© sur la nature d’un message, ALTOSPAM peut gĂ©nĂ©rer un dĂ©lai de l’ordre d’un quart d’heure Ă  une demi-heure liĂ© Ă  l’utilisation de la technique avancĂ©e de Greylisting.

  • How can you be sure that an important email isn't mistakenly spammed using Altospam's Mailsafe solution?

    Il s’agit lĂ  de toute la problĂ©matique des faux positifs. Le logiciel antispam et antivirus Mailsafe d’Altospam combat ce problème sur trois fronts:
    1- en limitant au maximum le taux de faux positifs,
    2- en assurant que, dans le cas de dĂ©tection d’un mail comme faux positif, l’expĂ©diteur soit informĂ© que son mail n’est pas parvenu Ă  son destinataire,
    3- en vous permettant de visualiser l’historique des messages traitĂ©s via l’interface d’administration ou via la rĂ©ception quotidienne d’un mail de synthèse de vos logs afin d’identifier et de libĂ©rer d’Ă©ventuels faux positifs. 

  • What is the guaranteed availability of ALTOSPAM servers?

    Chaque client ALTOSPAM dispose de plusieurs serveurs ALTOSPAM pour assurer une haute disponibilité en cas de problème sur un des serveurs. De plus, les serveurs ALTOSPAM sont situés sur des sites géographiques différents pour anticiper tout problème de connexion à Internet ou autre. Une garantie de disponibilité du service (SLA) est également intégrée dans nos contrats utilisateurs. Pour plus de détails, le flux Garanties et services Altospam présente certains de ces différents aspects.

  • What happens if my mail server is down for several hours?

    Mailsafe d’Altospam assure une “bufferisation” de vos emails pendant 5 jours. Votre serveur peut donc rester indisponible pendant plus de 120 heures sans que cela ne pose de problème. Au-delĂ  de ce dĂ©lai, un message d’erreur est envoyĂ© aux expĂ©diteurs.

  • Why use an ASP outsourced solution like ALTOSPAM? Can we install Altospam's Mailsafe on our company's mail server?

    L’intĂ©rĂŞt est multiple: d’une part vous ne saturez ni votre connexion Internet ni votre serveur de messagerie avec des emails illicites, d’autre part vous ne vous prĂ©occupez de rien : vous n’avez aucune installation et mise Ă  jour Ă  effectuer. La solution ALTOSPAM est proposĂ©e exclusivement en mode ASP, il n’est pas possible d’installer de serveurs antispam ALTOSPAM dans votre sociĂ©tĂ©.

  • Do I need a domain name?

    OUI, la solution ne peut ĂŞtre mise en place que pour les structures possĂ©dant leur propre nom de domaine. Mailsafe d’Altospam propose en option d’enregistrer votre nom de domaine si vous n’en possĂ©dez pas.

  • How long is Altospam's Mailsafe service contract and can I opt out at any time?

    Par défaut, la durée du contrat est de 1 an, renouvelé par tacite reconduction.
    Le contrat peut cependant être rompu à tout moment par lettre recommandée en respectant un préavis de quinze jours.

  • Is my company's use of Altospam's Mailsafe solution transparent to my email correspondents?

    La solution anti-spam et anti-virus Mailsafe d’Altospam est complètement transparente pour l’expĂ©diteur de messages dont vous ĂŞtes le destinataire. Les serveurs ALTOSPAM sont configurĂ©s comme serveurs de mails de votre sociĂ©tĂ© au niveau de votre DNS ; ils redirigeront ainsi les mails licites vers votre serveur de messagerie.

  • Altospam's Mailsafe is an outsourced solution, so where does my company's email go? How are the security and confidentiality of our e-mails guaranteed?

    Tous les serveurs ALTOSPAM sont physiquement prĂ©sents dans des datacentres français. Les serveurs sont hautement sĂ©curisĂ©s de manière Ă  garantir l’intĂ©gritĂ© et la confidentialitĂ© de vos communications Ă©lectroniques. De plus la confidentialitĂ© des messages est garantie contractuellement.

  • I use a mail server provided by an outsourced host. Can I still use Altospam?

    Au mĂŞme titre que si votre serveur Ă©tait situĂ© dans vos locaux, si votre serveur de messagerie est hĂ©bergĂ© chez un tiers ou bien s’il s’agit d’un service mutualisĂ© proposĂ© par un hĂ©bergeur spĂ©cialisĂ©, cela ne change rien, vous pouvez profiter du service antispam et antivirus ALTOSPAM.

  • What message analysis techniques does Altospam Mailsafe use?

    ALTOSPAM est basĂ© sur un procĂ©dĂ© extrĂŞmement perfectionnĂ© de notation des emails s’appuyant sur de multiples techniques d’analyse : RBL (listes noires), analyse heuristique, mĂ©thode bayĂ©sienne, bases de spams, vĂ©rification des URL, enregistrement DNS,… (Cf. liste des technologies anti-spam utilisĂ©es). Mais le plus important rĂ©side dans l’action rĂ©alisĂ©e suivant la notation du message : accepter, refuser temporairement (technique de Greylisting), rejeter de façon permanente l’email ou maintenir la session ( Teergrubing). Ces actions, notamment la technique duGreylisting, permettent d’accroĂ®tre très significativement les rĂ©sultats d’analyse.

  • What is Greylisting?

    Le Greylisting consiste Ă  refuser temporairement un message. Si l’Ă©metteur est un vĂ©ritable serveur de messagerie (cĂ d spĂ©cifique Ă  la RFCSMTP) le message sera forcĂ©ment rĂ©Ă©mis puis acceptĂ©. Dans le cas contraire il sera rarement rĂ©expĂ©diĂ©. C’est la raison pour laquelle ALTOSPAM utilise cette technologie en cas d’ambiguĂŻtĂ© sur la nature du message. En contrepartie cette technique gĂ©nère un temps de latence dans la rĂ©ception des emails (Cf. article sur le greylisting).
