ExchangeDefender Supernet
Last month we announced a major upgrade and expansion of our network to better serve our clients in a more challenging cybersecurity world. I’m sure you’ve seen many stories in the news about cyber attacks and how some groups and nations are expected to attack our critical infrastructure.
We can assure you that those threats are real and are ongoing in a very focused fashion. In order to prepare for a more massive attack, we’ve had to rely on some BGP routing magic to make ExchangeDefender far more resilient.
Make sure you allow inbound SMTP traffic from ExchangeDefender’s 65.99.255.0/24 (255.255.255.0) range.
This range has been in use by ExchangeDefender since 2003 so if you’ve followed our deployment guide correctly you should be all set. If you’ve chosen to deploy ExchangeDefender differently and have other scanning/security active on that range, you might see email delivery delays and failures. Easy fix, just add the whole class C.
What is happening under the hood is that all of our different data centers are routing traffic via the same 65.99.255.x range. Even if half of our data centers disappear due to a telecom or power event, we will be able to continue email delivery.
As you’ve seen over the past year, we’ve focused on Inbox, LiveArchive, and upcoming Replay features to improve security and reliability. Like you, we wake up every day to another Exchange/Gmail event/issue/policy/fubar and nobody likes losing email or the ability to communicate. This is why having ExchangeDefender around your email infrastructure is critical if email is critical to your organization. The new supernet has been routing messages for over a month with no issue and on Wednesday, May 15th we will make it available for everyone.
ExchangeDefender Network Upgrade: Supercharged Security and Disaster Recovery for Your M365 Clients
At ExchangeDefender, we’re obsessed with keeping your clients’ emails safe and secure. That’s why we’ve just completed a massive network upgrade, designed to empower you, the IT Managed Service Provider, to offer unparalleled disaster recovery and enhanced security for your M365 clients.
Why the Upgrade? The Cloud Needs Saving Too!
Remember the good ol’ days of on-prem email outages? Well, guess what? The cloud isn’t immune!
- M365 Outages Happen: We’ve all been there – clients waking up to a down Office 365 tenant. Scary stuff.
- Data Loss Lurks: Lost emails due to strange glitches or language barriers (seriously, Croatian?) are a real threat.
Building on LiveArchive, we’re massively expanding our disaster recovery businesses due to increased demand for client protection on the Microsoft M365 network.
Our upcoming live mail caching service is here to save the day! We’ll cache copies of your clients’ emails for 24 hours, ensuring no email gets lost due to infrastructure issues. Need a message from the past day? Simply request a redelivery – problem solved!
Network Upgrade? More Like a Network Revolution!
To make Live Mail Caching a reality, here’s how we did it:
- Open-sourced LiveArchive: This empowers you to deploy massive email archiving solutions for your clients on their own cloud.
- Infrastructure Overhaul: We’ve upgraded nearly every switch, firewall, core router, and most of our backend to handle the massive data demands of live caching.
- Network Failover on Autopilot: BGP magic ensures seamless service delivery across multiple data centers, automatically routing around network issues and regional outages. No configuration changes on your end are needed!
In the coming quarter, we’re excited to unveil all these new services.
While email remains a prime target for cyberattacks (not a good thing!), our core focus continues to be protecting traffic and identifying threats. However, our M365 clients are facing a surge of issues and are turning to us for solutions.
For instance, when Microsoft experiences delivery delays or mail latency problems, our ExchangeDefender Inbox service becomes the go-to solution for accessing critical OTP/MFA tokens.
Many clients have also adopted Inbox as their preferred webmail client due to its speed and lightweight design.
As Microsoft prepares to sunset Basic Authentication, many legacy SMTP services and mail-enabled applications will become inoperable. To address this growing demand for reliable and secure email routing and delivery, we’ve significantly upgraded our network and services this past quarter.
Email delivery problems happen.
With ExchangeDefender, however, these problems won’t impact your operations. That’s our unwavering commitment, and we’re thrilled to announce the expanded ExchangeDefender network is here to serve you and ensure the continued security of your email.
P.S. Sounds expensive and boy was it!! We’re in an era where any excuse is used to raise prices, so this might come as a bit of a surprise: There will be no change in pricing as a result of all these upgrades. Thank you for keeping us in business in our 4th decade and thank you for trusting us with your email.
