Flexible email security deployment – The key to effective organizational protection

Email security has become a critical component of cybersecurity for businesses of all sizes

Based on conversations with our clients and our own experience, we see that organizations are looking for security solutions that are not only effective but also easy to implement and flexible enough to adapt to evolving business needs.

Companies across various industries face similar challenges:
➡ Advanced cyber threats – phishing attacks, invoice fraud, and data breaches.
➡ Limited IT resources – overburdened IT teams that lack time for complex configurations.
➡ Infrastructure evolution – as more businesses migrate to the cloud, new email security measures are required.
➡ Regulatory compliance – organizations must meet GDPR, NIS2, and other data security regulations.

This is why flexibility in email security deployment has become a key factor when choosing the right solution. Working closely with our partners and clients, we see the growing popularity of Barracuda Email Protection, which offers three deployment models, allowing businesses to tailor security to their unique needs.

Why Is Flexible Deployment So Important?

Businesses already recognize that they cannot compromise on email security, but at the same time, they want to avoid time-consuming implementations and complex administration. Flexibility in deployment allows organizations to choose the best protection method for their needs—both now and in the future.

Here are the key email security deployment options we most frequently recommend to our clients:

MX Record-Based Deployment – A Classic Approach for Businesses That Value Tradition

✔ A time-tested email security method used for many years.
✔ A security gateway analyzes emails before they reach recipients.
✔ Requires DNS record updates, which may be simple for some organizations but challenging for others.

Best suited for:
➡ Organizations that do not plan to change their infrastructure and prefer a traditional email security approach.
➡ Businesses with an IT team experienced in DNS configuration and managing MX records.

Inline Deployment – Ideal for Microsoft 365 Users

✔ Redirects email traffic using mail flow rules in the Microsoft 365 Exchange Admin Center.
✔ No need to modify MX records.
✔ Provides better protection against reconnaissance attacks since MX records do not expose email configuration details.

Best suited for:
➡ Companies using Microsoft 365 that want full control over their email security while avoiding DNS record management.
➡ Organizations that prefer simplified security administration and a quick deployment process.
