Email security advisory and best practices for a stronger, more resilient environment.
Independent, practical advice to help you assess, improve and maintain your email security strategy, configuration, operations and governance across Proofpoint, Microsoft 365 and supported multi-vendor environments.
Email security review — illustrative findings
Example findings showing how observations and recommendations may be structured during an assessment.
What we help you achieve
Strategic and technical advisory to strengthen your email security posture, operational readiness and ability to make informed changes.
Email security assessments
Conduct a structured review of mail flow, authentication, security policies, integrations and operational practices to identify configuration gaps, risks and opportunities for improvement, with clear prioritized findings.
Migration and change guidance
Provide practical guidance for Microsoft 365 migrations, platform changes, coexistence planning and configuration updates.
Architecture and design recommendations
Review mail-flow architecture, integration design and platform configuration and provide recommendations aligned to your environment.
Security improvement roadmap
Translate findings into prioritized remediation actions, dependencies and practical next steps based on risk, operational impact and implementation complexity.
Policy and best-practices review
Assess existing policies, exceptions and operational controls and provide best-practice guidance to improve security while reducing avoidable complexity.
Documentation and operational readiness
Develop or review technical documentation, runbooks, dependencies and operational procedures required to support the email environment.
Authentication strategy and governance
Advise on SPF, DKIM and DMARC strategy, domain governance, sender onboarding and ongoing authentication management.
Knowledge transfer and advisory sessions
Provide specialist guidance, walkthroughs and knowledge transfer to help your team understand decisions and maintain a strong email security environment.
Our advisory process
A structured approach to assess, interpret and guide improvements to your email security environment.
Understand
Establish the environment, objectives, scope and business requirements.
Assess
Review architecture, configuration, policies, authentication, evidence and documentation.
Analyze
Interpret the evidence to identify risks, gaps, dependencies and improvement opportunities.
Recommend
Develop practical recommendations and a prioritized improvement roadmap.
Guide & Support
Assist with agreed remediation, configuration changes or implementation planning.
Review & Improve
Validate outcomes and provide further guidance where ongoing advisory support is required.
Example: Security assessment summary
An illustrative example showing how we assess and summarize key findings from an email security review.
- Environment
- Proofpoint → Microsoft 365 (Exchange Online)
- Assessment scope
- Mail-flow architecture, policies, authentication, TLS and operational readiness
- Key findings
- Configuration gaps, excessive exceptions and incomplete authentication alignment
- Recommendations
- Simplify routing, standardize policies, complete authentication alignment and improve operational documentation
- Outcome
- Clear findings and a prioritized roadmap for ongoing security improvements
EMAIL SECURITY ASSESSMENT SUMMARY Environment: Proofpoint + Microsoft 365 Assessment areas: mail flow, policies, authentication, TLS, operations Overall observation: improvement opportunities identified Key findings: - Multiple mail-flow paths and legacy connectors - Policy exceptions and inconsistent settings - Incomplete authentication alignment for some senders - Limited operational documentation Recommended actions: 1. Simplify mail-flow architecture 2. Standardize policy configuration 3. Complete authentication alignment 4. Improve documentation and runbooks
KEY FINDINGS Architecture: redundant or legacy routing paths identified Policies: exceptions require review and consolidation Authentication: selected sending sources require alignment work Operations: documentation and runbooks need improvement
RECOMMENDATIONS 1. Remove unnecessary routing dependencies 2. Consolidate policy exceptions and standardize settings 3. Complete SPF/DKIM/DMARC alignment for authorized senders 4. Establish clear operational ownership and documentation
IMPROVEMENT ROADMAP Priority 1: stabilize and simplify mail flow Priority 2: review policies and exceptions Priority 3: complete authentication alignment Priority 4: improve operational documentation Priority 5: validate outcomes and review remaining gaps
NEXT STEPS - Confirm agreed remediation priorities - Assign owners for configuration and documentation changes - Implement approved changes in controlled stages - Validate mail flow, policy behaviour and authentication - Review remaining findings after remediation

Frequently asked questions
Common questions about our email security advisory and best-practices services.
What is included in an email security assessment?
The scope is agreed first, but an assessment can include mail-flow architecture, platform configuration, policies, authentication, TLS, integrations, operational practices and supporting documentation.
Can you help with Microsoft 365 migrations or platform changes?
Yes, where supported and within scope. We can review dependencies, mail flow, connectors, policy implications, authentication and operational considerations before or during planned changes.
What email security platforms do you support?
Our primary consulting focus includes Proofpoint, Microsoft 365 / Exchange Online, Cisco Secure Email and related email-authentication technologies. Other connected platforms can be considered where they are relevant to the overall architecture or engagement scope.
Do you review DMARC, SPF and DKIM as part of an assessment?
Yes, when authentication is within scope. We can review sender authorization, DKIM signing, DMARC alignment, policy and available reporting evidence alongside the wider email environment.
Do you provide configuration recommendations or implement changes?
Both approaches can be considered. Some engagements focus on findings and recommendations; others can include agreed implementation assistance, remediation guidance or validation after changes.
Will you provide documentation and runbooks?
Documentation support can be included where required, including current-state findings, recommended changes, operating procedures, dependencies and knowledge-transfer material.
How is an advisory engagement scoped?
The scope depends on the platforms involved, environment complexity, assessment depth, objectives, available evidence, required deliverables and whether implementation or follow-up support is included.
Can you provide ongoing advisory support?
Ongoing advisory support can be considered where it forms part of the engagement, including periodic reviews, change planning, configuration guidance, roadmap updates and follow-up assessment work.
