Because email is the entry point for more than 90% of cyber attacks, protecting it stops threats before they spread to other systems. MSPs manage multiple client networks, so a single compromised inbox can jeopardize an entire ecosystem. Offering email security demonstrates proactive risk management and differentiates the MSP in a crowded market. It also protects the MSP’s own reputation by reducing the chance of being used as a launchpad for attacks.
Phishing, Business Email Compromise (BEC), ransomware‑laden attachments, and credential‑stealing links dominate today’s threat landscape. Attackers constantly tweak social‑engineering tactics to bypass filters, making static rules insufficient. SMBs often lack dedicated security teams, so they rely heavily on their MSP’s defenses. Continuous monitoring and adaptive filtering are essential to stay ahead of these evolving threats.
A single breach can cost anywhere from $30,000 to over $200,000 in downtime, legal fees, and lost revenue. According to recent studies, 70% of small businesses shut down within a year after a major data loss event. The financial hit includes remediation, customer notification, and potential regulatory fines. Early email protection helps avoid these cascading costs by stopping attacks at the source.
MSPs should deploy DMARC, SPF, DKIM, and BIMI as a baseline. DMARC provides policy enforcement and reporting, SPF validates sending servers, DKIM ensures message integrity, and BIMI adds brand logos for trusted delivery. Together they create a layered defense that blocks spoofed emails and improves inbox placement. Check your DMARC health with Palisade’s Email Security Score.
DMARC tells receiving servers how to handle unauthenticated messages, reducing spam and phishing deliveries. By publishing a DMARC policy (none, quarantine, or reject), organizations gain visibility into abuse and can enforce stricter controls. This leads to higher sender reputation and better inbox placement. Learn more about DMARC at Palisade.
BIMI (Brand Indicators for Message Identification) displays a verified logo next to authenticated emails, reinforcing brand trust. When recipients see a familiar logo, they’re less likely to fall for phishing attempts that mimic the brand. Implementing BIMI also signals to inbox providers that the sender follows best practices, which can boost deliverability. Explore BIMI setup with Palisade.
DKIM adds a cryptographic signature to outgoing messages, which receivers can verify using a public key published in DNS. If the signature fails, the email is flagged or rejected, preventing attackers from forging the sender’s address. This verification works alongside SPF and DMARC for comprehensive protection. Set up DKIM using Palisade’s tools.
SPF (Sender Policy Framework) lists authorized IP addresses that can send mail for a domain. Receivers check the SPF record to confirm the source, blocking unauthorized servers. Although SPF alone can be spoofed, it remains a vital component of the authentication stack when combined with DKIM and DMARC. Configure SPF with Palisade.
Yes. Cloud platforms eliminate the need for on‑prem hardware, provide scalable processing, and offer centralized dashboards for multiple clients. They enable real‑time threat intel updates and simplify policy management across diverse environments. Cloud solutions also make it easy to grant clients read‑only access for transparency.
Sandboxing isolates attachments and URLs in a safe environment, allowing the system to analyze behavior before delivery. This technique catches zero‑day exploits and malicious code that traditional scanners miss. By preventing dangerous content from reaching end users, sandboxing reduces infection risk and limits potential damage.
Automation tools pull DMARC reports, generate alerts for failed authentication, and visualize trends in a single pane. Scheduled summaries keep clients informed without manual effort. Integrations with ticketing systems allow rapid incident response, turning alerts into actionable tickets.
Key criteria include comprehensive authentication support (DMARC, SPF, DKIM, BIMI), AI‑driven threat detection, easy multi‑tenant management, and transparent pricing. A provider should also offer APIs for custom reporting and seamless integration with existing MSP dashboards.
Begin with a simple risk snapshot: show how many phishing emails their users receive daily and the potential cost of a breach. Use plain language, avoid jargon, and focus on business impact. Offer a free assessment to demonstrate value and build trust.
Clients increasingly demand holistic protection, not just network or endpoint services. By bundling email security, MSPs create a one‑stop shop, increase contract stickiness, and open upsell opportunities for advanced threat protection.
Secure the MSP’s domain with DMARC, SPF, DKIM, and BIMI, enforce strong MFA, and monitor outbound traffic for anomalies. Regularly audit third‑party tools and ensure all admin accounts use unique, complex passwords. A hardened MSP email environment sets the standard for clients.
Email authentication verifies that a message really comes from the domain it claims to be from, using protocols like SPF, DKIM, and DMARC. It helps prevent spoofing and phishing.
BIMI signals to inbox providers that the sender follows authentication best practices, which can boost sender reputation and increase the likelihood of landing in the primary inbox.
No. Sandboxing complements antivirus by analyzing suspicious content in a controlled environment, catching threats that signature‑based tools might miss.
At least monthly for new domains, and weekly for high‑risk environments. Frequent reviews help spot misconfigurations early.
Multi‑tenant platforms are designed for MSPs, offering centralized management and cost efficiency, while still maintaining isolation between client data.
