Anyone who uses email knows that spam is an incredibly huge nuisance. However, it’s not just a nuisance and inconvenience anymore. It’s now a costly issue for businesses, and it can lead to a data breach if spam emails persuade users to access malicious websites in their browsers on business devices. Spam filtering in Microsoft 365 is not as difficult as you think provided that you have an effective and cost-efficient way to implement it across your network environment.

The Danger of Spam Emails to Business Operations

Spam costs businesses money in several ways. The first one is the amount of spam sent to various inboxes costs money to store. Billions of spam messages go out every day. Forbes reported in 2020 that 320 billion spam messages go out every day, and that number continues to increase yearly.

With effective email services, emails are blocked from accessing recipient inboxes. Microsoft 365 users are large targets because they are usually inboxes for businesses. When a spam message (or any message for that matter) reaches a target recipient’s inbox, the server must store these messages in its storage reservoirs. Now imagine that billions of email message are sent every day, and you can conclude that storing these messages are expensive. If just a fraction of these messages reach your business email server, you pay the cost of storing them. Because spam messages are a nuisance, you pay the cost of storing nuisance messages.

Nuisance isn’t the only danger of allowing email messages to reach your user inboxes. Another issue is the contents of these messages. Users must spend business hours reading them, and then many of the messages contain malicious links. They are not necessarily phishing email messages, but they contain links to illicit websites that could affect the security of the user’s device or the business network.

Aggregate the time it takes for users to read spam messages and the time it takes for administrators to manage them (e.g., blocking them or instructing users on what to do with spam messages), the business loses money on what could be described as an unnecessary nuisance and potential security issue.

What You Need to Protect Microsoft 365 User Inboxes

Microsoft 365 spam filter is necessary to stop messages that could cost the business unnecessarily and protect data. Some businesses decide to focus on employee education, but this leaves the business open to human error, insider threats, and bypasses of security protocols.

Microsoft 365 has its own built-in spam blocking features, but they are ineffective at stopping sophisticated campaigns targeting enterprise businesses. For example, the Office 365 spam filter has a real-time blocklist, but it’s reactive based on customer reports. A solution such as SpamTitan is proactive at blocking based on artificial intelligence (AI) and heuristics on common behaviour patterns.

Spam messages often contain malicious URLs, which could fall into phishing. It takes sophisticated technology to proactively detect these malicious URLs rather than rely on users to report them. SpamTitan Plus has the technology and AI-driven features to block spam emails from ever reaching the user’s inbox. It contains a predictive analysis of email content to fully protect users from accidentally clicking malicious URLs and putting it on untrained individuals to properly identify a malicious message from a harmless one.

Spam titan let’s me focus on more important matters

What do you like best about SpamTitan Email Security? I found spamtitan via reddit 2 years ago and I cannot tell you how much time it has saved me. I am the sole IT person for a company of around 100 employees and before spam titan there would be days where half of my morning, every morning, was sorting through questionable emails that looked like legit invoices but werent. In the last year over 170k crap emails were stopped before reaching our mail servers. If I scanned every one of those emails manually with 1 minute scan time each. That's 118 DAYS worth of time spam titan has saved me. Their interface is to the point and not unnecessarily flashy. We use spam titan cloud and it is FAST. I can pull up a weeks worth of emails for all employees in 10 seconds and manually check if there was something blocked that shouldn't have been (rarely happens though). I can view suspicious emails without needing to download them first, I can create custom block lists by domain or email address. And I actually just found a digest feature that let's me send all employees a quarantine report allowing them to unblock things they need from their own email without needing me to stop, find the email, and white list it. Our plan has a set number of emails but unlimited domains so we have 4 companies using spam titan all under the same plan. I can add or remove companies on my own without messing with our cost or needing assistance from spam titan support. Lastly, spam titan support staff are AMAZING. it's ridiculous how helpful and friendly they are. The most recent example being that my email host started acting up and emails were vanishing. Spam titan support, as well as my account manager for spam titan looked into our delivery logs and informed me what they saw on their end. They then went out of their way helping me understand how to setup another companies product to work with their own when they didn't have to. I love these guys. The cost is absolutely worth the piece of mind and I'm a cheap skate to boot. I have never been happier with another company in my entire IT career. What problems is SpamTitan Email Security solving and how is that benefiting you? I'm saving time, money, and getting the benefit of virus scanning before email even reaches our own firewall and network. In IT the biggest security risk is always employees unfortunately. This cuts that risk down for email alone by I'd say at least 90% making my job so much easier.

Cloud Version is Great for Managed Services Providers

What do you like best about SpamTitan Email Security? The support is great and the cloud platform seems to work very well at integrating with either on-site Exchange servers or Office 365. I also like the single daily email to each user giving them the opportunity to review blocked messages and take action. Many other platforms swamp users with notifications every time something is blocked. This is very simple for us to setup and users to understand. What problems is SpamTitan Email Security solving and how is that benefiting you? We are an MSP with clients of all sizes that desire managed spam protection. They need the ability to see what messages are blocked and whitelist if necessary, in a format that all of their users can understand. We appreciate the simple, clean interface that gives us the ability to quickly setup new clients, as well as quickly find and take action on messages that the client needs to find right away. The support has been great, as we are constantly swamped with duties and responsibilities of our own and do not have time to spend hours learning how to use a new platform or troubleshoot an issue.

Antispam that is affordable, flexible and powerful

Spam filtering was costing us a lot of money, and then the vendor said we had to replace their appliance with a new one (about $3000 just for the appliance). SpamTitan costs much less per year, and we'll never have to replace an appliance again. We got SpamTitan's clustered solution, so we have a second VM running at our DR site, the two sync (or re-sync if there has been an outage), giving us load-balancing and fault-tolerance, and at a still significant savings.

Simple and Easy to use

What do you like best about SpamTitan Email Security? Having a simple online interface where we can monitor in realtime the emails coming through the system. Blocking persistent emails by domain or email address and White listing email addresses is easier for all users. At any point emails can be released to the user and daily summary makes it great for the user to highlight any false positives. What do you dislike about SpamTitan Email Security? I've not had an issue with the system since going live 12 months ago. Recommendations to others considering SpamTitan Email Security: Use the free trial to see if it compatible with your needs first. This gave us total confidence that it was going to meet our needs. What problems is SpamTitan Email Security solving and how is that benefiting you? Easy access to the spam filer, quarantine and users. If a new client has emailed and we have not received the email we can easily check the filter first. Their email can then be whitelisted. We have been able to bypass our external IT support and have one main user who can control this in house saving so much time.

Benefits of Using an Effective Microsoft Office 365 Spam Filtering Tool

Using the SpamTitan Plus email filtering tool, you lower cybersecurity risks for phishing attacks and reduce the size of inboxes, essentially lowering your network storage costs. It also helps with the analysis of incoming and outgoing messages and provides administrators with the information needed to review email activities.

SpamTitan works in both an on-premises environment and cloud-based email servers. For MSPs, it means that you can roll out necessary email security for all customers and manage their policies from a single location. It also helps MSPs determine if their customers are targets of sophisticated spam and phishing campaigns so that the MSP can alert business employees to be on the lookout for malicious messages should one slip through.

Malicious messages are quarantined, so administrators and MSPs can also review messages to reconfigure policies should they find a false positive. Although SpamTitan has few false positives, policies might need to be changed to ensure that false positives are limited and legitimate messages always reach the intended recipient.

With SpamTitan, MSPs and local administrators can deploy an effective solution to manage email and stop malicious messages at an affordable price. We have advanced phishing protection, so you can eliminate human error from the risks of a data breach.
