Cloud email security & anti-spam solution

4.77/5 (119 reviews)

ZEROSPAM overview

ZEROSPAM is a complete cloud email security and anti-spam solution that helps protect organizations from all email-borne threats including ransomware, malware, phishing, spear phishing, DOS attacks, dangerous links, harmful attachments, and more. ZEROSPAM’s ransomware detection features properly secure the two main propagation vectors: disguised executable files and infected macros in Microsoft Office documents sent as attachments via email messages, or downloaded by users through a malicious link.

ZEROSPAM provides complete protection against all forms of harmful and undesirable email messages from reaching the inbox. With its ransomware and malware detection tool, users are able to secure their emails against viruses, Trojans, spyware, adware and worms which are spread via executable files, sometimes renamed to .pdf, .gif, .jpg, .txt, .eml, or .png files as a disguise. ZEROSPAM also scans every link contained in each and every email, and analyses them to ensure they are safe using two different antivirus engines, and other tools. When a dangerous link is detected, the email message is automatically quarantined and marked with a warning symbol. The solution also enables full blocking of infected macros in Microsoft Office documents, and integrates with Sanesecurity's signature database for added protection.

ZEROSPAM’s Cumulus web portal enables administrators to monitor communication and quarantine and logs, as well as modify filtering parameters such as whitelists or blacklists. Users can also configure advanced functions including access security policies, LDAP synchronization, and single sign-on. Sessions and modifications are audited in order to be able to determine which user made what action, and when, if a problem arises. Detailed statistical reports containing numbers on rejected connections, quarantined messages, blocked emails, phishing attempts, and more, can be sent by email once a week to any user, or aggregated into monthly statistical reports.

already written in the last pageI have nothing to do for this spam filtering solution to work perfectly every day!! I know it sound impossible but it's a fact. No hardware to maintain, no VM, no software to update. I do not remember the last time i had to release an email from the quarantine, at least 8 month ago. Installation: A DNS Change only. Simply redirect your MX record to the one Zerospam will give you. That's it. A second step to do that is optional: Firewall filtering/limiting tcp/25. My email server is protected from the bad guys who want to connect to my email server because it only accept SMTP connection on the port 25 from the Zerospam server. The path an email do : you, Zerospam, me. Isolation = safety. Bandwith saving. Because the spam did not come in my infrastructure, they do not use my bandwith and ressource. Virus protection, it add another layer of protection. Support, they are fast to answer to email and i can speak to a human easely. Yes, a real human. It's a Canadian business with server around the world. Usage: A web site will give you the possibility to whitelist, blacklist, use greylisting, access to statistics. last week 95,98% of SPAM!!! This number vary every week. Quarantine, an email can be release from there. You can filter by date, user from or to, subject. Stop reading and use the free trial.

I don't have to manage or worry about hardware antispam appliances, updates, or software to deploy on my network. Their service is entirely managed by Zerospam in the cloud. I love it.It just works, and I don't need to worry about it. Their online control panel is intuitive and simple to use. You don't have to worry about hardware, installing software or anything like that. Their service is fully managed and monitored by them. Even if you don't know much about IT or DNS, their support team is really great and provides you all the information you need to activate their service. To me, the greatest thing about Zerospam is actually being able to SPEAK to a real human being, instead of bouncing emails back and forth to outsourced support like other antispam providers are doing.

I am very happy, my clients are happy, what more can you ask for?It does what it says and removes practically all the spam my clients have never been able to get removed before. Many used all in one solutions from Brand Name companies but still a lot of spam got through, and the constant update of the software and adjustments took a lot of time. Zerospam does all that for you at a very reasonable cost, so I can spend my time on more important issues.

Company was easy to do business with from review, pilot to acceptance and installation.

security !Very easy to adopt. Easy transition from pilot to production. Good details as it relates to a summary report automatically forwarded on a weekly basis providing relevant information related to each email that had action applied. I was surprised we were receiving so much garbage which previously would have been delivered to our user base. Having the e mail filtered at the envelope level prior to even arriving at our site is great eliminating the " fake news ". The cost per mail box for the features provided is good value compared to some of the major players in the field

Practically no more spams. An additional view on our mail flow. A buffer that will keep the incoming mail waiting while we work on the mail server.Easy to use tools for control over white/black lists, reports, and logs to diagnose why an email does not come through. Very good control over spam/virus/phishing, they have practically disappeared from our email flow. The occasional one gets through sometimes, but it's not long before the system notices and begins blocking it.
