Business email protection
Your email is essential. Keeping it secure matters.
Businesses depend on email for customer communications, financial transactions, collaboration and sharing important information.
Unfortunately, attackers also use email to deliver phishing messages, fraudulent payment instructions, malicious attachments and account takeover attempts.
Effective email security combines protective filtering, domain authentication, account security and employee awareness to reduce the likelihood of successful attacks.
IRON IT Group can help assess your email environment and recommend security improvements suited to your organisation.

Inbound email protection
Stop more suspicious messages before employees interact with them.
Many cyberattacks begin with a message that appears legitimate. It may contain a fake login page, an unexpected attachment or a request that appears to come from a trusted colleague.
Modern email security technologies can examine incoming messages using reputation checks, authentication signals, malicious-link detection and other available analysis techniques.
The goal is to reduce the number of suspicious messages employees encounter and improve visibility into threats targeting your organisation.
- Spam and malicious message filtering
- Phishing and impersonation detection
- Suspicious attachment analysis
- Malicious URL protection
- Sender reputation checks
- Quarantine and message review
- Security policy configuration
A layered security approach
More protection between threats and your inbox.
Message Filtering
Identify and quarantine suspicious or unwanted messages using supported email security controls.
Link Inspection
Evaluate potentially unsafe URLs and reduce exposure to known malicious destinations.
Attachment Analysis
Review supported attachments for malware and suspicious behaviour.
User Protection
Combine technical controls with staff awareness to help reduce the success of social engineering.
Domain authentication
Help stop attackers impersonating your business domain.
SPF, DKIM and DMARC work together to help receiving email providers verify messages and apply your domain's authentication policy.
SPF
Sender Policy Framework
SPF identifies the mail servers authorised to send email using a domain's envelope sender information. It is one part of domain authentication and must be correctly aligned for DMARC evaluation.
DKIM
DomainKeys Identified Mail
DKIM adds a cryptographic signature to email messages, allowing receiving systems to verify the signature and determine whether signed message content was altered.
DMARC
Domain-based Message Authentication
DMARC checks whether SPF or DKIM authentication aligns with the visible From domain and lets domain owners publish handling policies and receive authentication reports.
Correctly configured DMARC helps reduce direct domain spoofing, but it does not eliminate lookalike-domain attacks or all forms of phishing.
Managed DMARC
Strengthen trust in your business email domain.
Discover Your Sending Sources
Identify legitimate services sending email on behalf of your organisation.
Configure Authentication
Review SPF and DKIM configuration for supported email services.
Review Reports
Analyse DMARC reports to identify authentication issues and potentially unauthorised senders.
Move Toward Enforcement
Plan a transition toward stricter DMARC policies after legitimate mail flows are validated.
Outbound protection
Make it harder for criminals to spoof your email domain.
Your company's domain is part of its identity. When criminals forge messages that appear to come directly from that domain, it can undermine confidence among customers, employees and business partners.
A properly implemented DMARC policy can help receiving systems reject or quarantine messages that fail the relevant authentication and alignment checks.
IRON IT Group can help you evaluate the necessary authentication records and develop a suitable DMARC implementation plan.
- Domain authentication assessment
- SPF configuration reviews
- DKIM configuration
- DMARC reporting and policy planning
- Legitimate sender identification
- Authentication troubleshooting
- Ongoing policy improvement options

Frequently asked questions
Email Security FAQs.
Answers to common questions about business email protection, phishing, DMARC and cloud email security.
Why is email security important for businesses?
Email is frequently used to deliver phishing attempts, malicious links, fraudulent payment requests and malware. Appropriate security controls can reduce the likelihood and impact of these attacks.
What is business email security?
Business email security includes technologies, configurations and processes designed to protect email systems and users against threats such as phishing, spam, impersonation, malware and account compromise.
Can email security prevent phishing?
Email security tools can identify and block many phishing attempts, but no solution can guarantee complete prevention. Employee awareness and strong account security remain important.
What is Business Email Compromise?
Business Email Compromise, or BEC, is a form of fraud where criminals impersonate trusted contacts or use compromised email accounts to request payments, financial information or sensitive business data.
What is SPF, DKIM and DMARC?
SPF identifies authorised sending systems, DKIM provides message signatures, and DMARC uses SPF or DKIM alignment with the visible From domain to support authentication policies and reporting. Together, they help receiving systems assess email authenticity.
Can DMARC stop people impersonating my company?
An enforced DMARC policy can help reduce direct spoofing of your actual domain at receiving systems that apply DMARC. It cannot prevent every impersonation attempt, including attacks using lookalike domains.
Does Microsoft 365 include email security?
Yes. Microsoft 365 and Exchange Online include various email protection capabilities, with additional features available through qualifying plans and security products. The appropriate configuration depends on your licences and requirements.
Do I need an additional email security service with Microsoft 365?
Not necessarily. Some businesses can meet their requirements using correctly configured native Microsoft security features. Others may benefit from additional filtering, archiving, continuity or specialised protection.
Can email security protect against ransomware?
Email filtering and attachment protection can help reduce exposure to ransomware delivered through email. Broader protection also requires endpoint security, patching, backups and incident response planning.
Does email security help with data protection compliance?
Email security may support an organisation's security obligations by reducing exposure to unauthorised access and data loss. Compliance depends on the overall technical, organisational and legal requirements, not simply on installing an email security product.
Can you help secure Google Workspace?
Google Workspace offers email authentication and security controls. IRON IT Group can discuss relevant configuration assessments and email protection options based on the environment being used.
How much does business email security cost?
Pricing depends on the number of users, email platform, selected security tools, authentication requirements and level of ongoing management. Contact IRON IT Group for a tailored discussion.
