Email security
Rua Technologies deploys hosted email security from Microsoft Defender for Office 365 and Trend Micro to filter spam, phishing, and business email compromise before it reaches inboxes.
Email remains the single most common entry point for attacks — most incidents we see start with a phishing email, not a firewall breach.
What's included
01Filter
Filtering that catches spam, known malicious senders, and phishing attempts before they land in a mailbox.
Best for: Any organization running Microsoft 365 or Google Workspace for email.
Typical timeline: Initial filtering setup typically takes 3–5 business days.
02Detect
Detection tuned for impersonation and account takeover attempts, which standard spam filters often miss.
Best for: Finance and operations teams that handle wire transfers or vendor payments by email.
Typical timeline: BEC protection policies are typically configured within the first week.
03Protect
Encryption and policy controls for sensitive information sent by email, without adding friction for routine mail.
Best for: Regulated businesses that need to control how sensitive data leaves by email.
Typical timeline: Encryption policy setup typically takes 1 week.
04Train
Simulated phishing campaigns and short training that measurably reduce click-through rates over time.
Best for: Organizations that have had a near-miss or actual phishing incident and want to reduce the human risk factor.
Typical timeline: First simulation campaign typically launches within 2 weeks.
05Authenticate
SPF, DKIM, and DMARC configured and monitored so attackers can't spoof your domain in phishing emails sent to your customers and partners.
Best for: Organizations that want to stop their own domain from being used to phish customers, partners, or vendors.
Typical timeline: DMARC rollout typically moves from monitoring to enforcement over 4–8 weeks.
06Respond
Rapid mailbox recovery and cleanup when an account is compromised, so a single phished login doesn't turn into a wider breach.
Best for: Organizations that need a fast, defined process the moment a mailbox is suspected compromised.
Typical timeline: Initial containment typically begins within 1 hour of detection.
FAQ
Both platforms include baseline filtering, but layered protection with tuned policies and BEC detection catches significantly more than default settings alone.
BEC is when an attacker impersonates an executive, vendor, or colleague to trick someone into a wire transfer or sensitive data disclosure — it often bypasses standard spam filters entirely.
Yes. Policies are tuned and tested against your actual mail flow before full enforcement, so legitimate email isn't caught up in filtering.
Yes. We run simulated phishing campaigns and targeted training, with reporting on click-through trends over time.
Yes. We deploy and tune email security for both platforms, including mixed environments during a migration.
