The global Business Email Compromise (BEC) market size is estimated at USD 1.38 billion in 2023 and is projected to grow at a CAGR of 22.4% from 2024 to 2030. In this situation, email security tools are becoming an essential means to protect sensitive information, prevent data breaches, and maintain business continuity.
Recent regulatory changes acknowledge the rising importance of email security. The Payment Card Industry Data Security Standard (PCI DSS) v4.0 now requires the use of anti-phishing measures by March 31, 2025. Google and Yahoo have made new sender authentication requirements for bulk email senders which require the use of SPF, DKIM, and DMARC protocols.
PCI DSS and Google/Yahoo Requirements
PCI DSS 4.0 Compliance
PCI DSS 4.0 has announced 51 new requirements, which will become mandatory from March 31, 2025:
- Enhancement in security documentation
- Improvements in internal assessments
- Frequent hardware and software reviews
- Multi-factor authentication
- Automated log monitoring
- Improved key and certificate management
One aspect of PCI DSS 4.0 is the requirement for anti-phishing measures. From March 31, 2025, organizations will be required to use anti-phishing mechanisms (e.g. DMARC, SPF, and DKIM to protect against phishing attacks).
Google and Yahoo Email Authentication Requirements
Starting in February 2024, Google and Yahoo are enforcing new email authentication requirements for those who send over 5,000 emails per day to Gmail or Yahoo users):
- Authentication: Implement SPF, DKIM, and DMARC protocols for all outgoing messages.
- Quick unsubscription: Provide a one-click unsubscribe process.
- Spam rate threshold: Maintain a spam rate below 0.3%, ideally under 0.1%.
If you do not comply with these requirements, your emails may be marked as spam, rejected, or not delivered.

Comprehensive reporting and analytics for threat intelligence
Advanced tools provide detailed insights into threat patterns and user behavior.
Benefits of Using Email Security Tools
Using email security tools offers numerous advantages:
They reduce financial risk: The average cost of a data breach in 2024 is $4.88 million USD. Email security tools can help you save both nerves and money.
They help to comply with industry regulations: Meeting PCI DSS v4.0 requirements and other industry standards can help organizations avoid potential fines and other issues (e.g. legal).
They provide improved threat detection: AI-powered tools can detect threats 13 days faster than traditional security methods.
They offer better protection: These tools can counter AI-generated phishing attempts, which have increased by 135% since the introduction of ChatGPT.
They boost employee productivity: Effective security measures can lead to a 6x improvement in phishing recognition within 6 months.
They improve brand protection: Email authentication protocols like SPF, DKIM, and DMARC play an important role in safeguarding brand reputation.
Top Email Security Tools
Here are some tools that can help you reach your email security goals in 2025:
Email Authentication Tools (SPF, DMARC, DKIM Tools)
SPF, DKIM, and DMARC are the three fundamental email authentication protocols that together create a holistic system for securing your email domain. They serve the objective of preventing spammers, phishers, hackers, and other unauthorized parties from impersonating your domain. According to recent studies, using these protocols can reduce phishing attacks by up to 99%. Organizations that fully deploy DMARC have seen a 10-fold decrease in email-based brand abuse.
To ensure the proper implementation and functionality of these protocols, it’s recommended to use specialized tools that automates the implementation process, and reduces human error.
SPF Generator & Checker Tools
An SPF record can help you prevent hackers from sending malicious emails on behalf of your domain. You first need to determine which domain servers are authorized to send emails on your behalf, and then use a SPF record generator to create an SPF record. Make sure to publish this SPF record in the DNS of your domain. Then, use an online SPF record checker to check the accuracy and validity of your SPF record. This will help you prevent breaches, blacklist suspicious sources, and detect spam at the earliest possible stage.
DKIM Generator & Checker Tools
With DKIM, you can easily check whether or not the data within an email has been manipulated by third parties in the transmission process. This will help you to effectively detect the security of your email communications and enable email senders to associate a given digital signature with emails coming from your domain. The first step is to use a free DKIM record generator tool to generate a DKIM record and publish it in your domain’s DNS. Then, check the validity of your record with a DKIM record lookup tool.
DMARC Generator & Checker Tools
A good DMARC checker will help you make a quick and easy DMARC record check to find any errors or gaps in your DMARC, gain key insights into your record’s configuration, and boost email deliverability rates. There are many DMARC checker tools currently available in the market that are completely free of charge, so you can enjoy an error-free DMARC record without spending a fortune.
Email Encryption Tools
Did you know that 60% of organizations now use email encryption to protect sensitive data? These tools help protect sensitive information during transmission and storage. Current encryption methods often use AES-256 or RSA-2048 algorithms which help safeguard email content and attachments. Features like end-to-end encryption let only the intended recipient read the message and prevent unauthorized use.
Email Security Gateways
Email security gateways can be viewed as the first line of defense and filter incoming and outgoing emails for threats. Many of the current gateways use AI to detect and block sophisticated attacks. This helps achieve over 99.98% success rate in identifying and blocking spam. These tools often include features like sandboxing to safely detonate suspicious attachments and URL rewriting to protect against malicious links. Some advanced gateways can also detect and block business email compromise (BEC) attacks, which have cost organizations over $43 billion since 2016.
Phishing Detection and Prevention Tools
These tools use a combination of AI, behavioral analysis, and threat intelligence to identify and block phishing attempts. Some advanced solutions can detect AI-generated phishing emails and provide real-time warnings to users. According to Verizon’s 2023 Data Breach Investigations Report, phishing was involved in 36% of data breaches.
Data Loss Prevention Tools
DLP tools can prevent the leakage of sensitive information via email. They encrypt, quarantine, or block emails that contain confidential data. Many of today’s DLP solutions use machine learning to understand context and intent. Some tools also provide optical character recognition to scan attachments. A recent study found that organizations that use DLP tools reduced data breaches by 35%.
Summing Up
Phishing attacks increased by 173% in Q3 2023, which is a significant rise compared to the previous quarter. Additionally, in 2023, 94% of organizations from all over the world fell victim to phishing attacks. This means that using email security tools is no longer a choice but a necessity. We hope this article provided you with the necessary knowledge to choose the right email security tools and prevent the next attack before it’s too late.
