Quick Answer

Email security has shifted from signature-based filtering at the gateway to continuous detection, machine-learning-based fraud detection, and post-delivery response. The drivers are the move to cloud email (Office 365, Google Workspace), the prevalence of BEC and spear-phishing, and zero-day attacks that bypass static filters. Modern controls include secure email gateways with multi-layered scanning, API-based post-delivery analysis inside cloud mailboxes, DLP and end-to-end encryption on outbound mail, two-factor authentication on email accounts, and ongoing phishing simulation programs to harden user behavior. Foundational protocols (SPF, DKIM, DMARC) remain essential. The market is projected at $6.8 billion by 2025\. The practical takeaway: combine API-based detection inside the mailbox with gateway filtering, MFA on accounts, and recurring user training, because attackers continue to innovate around any single layer.

![Email Security Solutions](https://media.mailhop.org/duocircle/images/2021/10/dkim-validation-2011.jpg) 

Today, sophisticated [phishing attacks](/resources/identify-and-neutralize-phishing-attacks), such as those leading to **ransomware and BEC** (Business Email Compromise) incidents, can easily bypass traditional security setups. _Emails are a common entry point for cyberattacks_. And the overwhelming number of cyber-attacks on emails of employees and business executives has made **email security** an important issue for organizations.

Security experts must approach email [phishing protection](/email/phishing-protection) in the same way they secure other traditional content repositories. Email service providers and [anti-phishing services](/email/phishing-protection) must prioritize giving their customers a detailed overview to help security teams improve their actions. If a malicious actor breaks into an email account, security teams may not know how they accessed individual messages.

## How Phishing Attacks Have Evolved

_Malicious actors profit through **phishing attacks** making use of the insecurity of their target users_. Phishing attacks have evolved to take new forms such as **spear-phishing** and advanced forms like [social engineering](/phishing-protection/social-engineering-is-a-growing-threat/), [business email compromise](/email-security/top-strategies-to-avoid-business-email-compromise-and-upgrade-email-security/) (BEC), and many others. In BEC, the malicious actor impersonates a higher official of the organization by using credentials resembling theirs and gains employees’ trust. They ultimately steal sensitive data or install malware. While the [FBI attributed](https://www.fbi.gov/news/stories/2019-internet-crime-report-released-021120) half of the cybercrime losses to business email compromise (BEC), BEC actors broadened their toolbox to compromise cloud accounts, organizations, and vendors. Stopping them will be an ongoing challenge.

While phishing attacks have dominated the email threat landscape for years, the increasing reliance on cloud email, the spread of SaaS and cloud-based platforms, and the fear of the pandemic have led to a resurgence of these attacks. Threat actors exploit the growing reliance on the cloud for [email hosting](/email/hosted-email) or [email forwarding](/email/email-forwarding) to steal sensitive data, spread dangerous malware, launch sophisticated attacks, and spread malicious campaigns across their existing networks. And the consequences of inadequate **email security measures** affecting the confidentiality, integrity, and availability of valuable data of an organization have never been more significant in the age of advanced threats.

[Trustwave’s 2021 Email Threat Report](https://www.trustwave.com/en-us/resources/library/documents/2021-email-threat-report/) shows real-life examples of recent email threats and key trends from the past year to help one understand the current situation to prepare oneself better with an _email security strategy for phishing and ransomware protection_.

[![Cloud-delivered Email Systems](https://media.mailhop.org/duocircle/images/2021/10/DMARC-generator-2474.jpg)](https://media.mailhop.org/duocircle/images/2021/10/DMARC-generator-2474.jpg)

## Cloud-delivered Email Systems

Beyond the onslaught of [zero-day attacks](https://www.phishprotection.com/content/zero-day-attacks/), there is a shift in **email security** from signature-based verification of email receipts to continuous detection and response. There is also the use of Machine Learning to detect fraudulent emails and the hunt for latent threats that elude initial detection and get activated after delivery. [Robust email security](/) at the gateway level to scan incoming emails for malware and cloud-based [email archiving systems](/content/email-archiving/) to store emails securely are among the cyber resistance strategies that address the risks associated with email security. With the number of cyber-attacks and the advanced threat of malware, spam, and phishing attacks increasing globally, businesses should increase the acceptance of **cloud-based email security**.

To give you an example, an essential component of Microsoft’s threat protection is that Office 365 provides **critical security alerts** when a threat arrives via email and helps provide essential protection in the early stages of an attack like in Microsoft’s other security technologies. _The broad visibility of email threats enables Office 365 to inform and improve its heuristics and protection with Machine Learning_. It helps block new and emerging attacks in real-time to protect customers from attacks they may not even know they are protected from.

## Latest Trends And Recent Evolution In Email Security

An ideal [email security solution](/) should be able to ward off threats such as phishing emails, BEC imitation attempts, malware, APT, and zero-days and prevent them from reaching end-users, providing multiple layers of protection. Besides, here are the latest trends related to how **email security solutions** are evolving in recent times.

- **Secure Gateways:** _A better solution is the use of secure email gateways with a multi-layered approach_. Email is integrated with applications such as file sharing and business collaboration suites, such as Office 365 and G Suite. It will lead to multiple entry points for malicious actors to exploit the system, meaning _email security measures must include robust account recognition and access management tools_. With that approach, a **secure email gateway** can ward off spam, prevent data loss, review content, encrypt messages, and much more.
- **Better Email Strategies By Vendors:** A cloud-based security system can help protect the business, customers, and employees from incoming malware and spam, phishing campaigns, zero-day attacks, and more. Policy-based security can integrate with secure email gateways such as DLP (Data Loss Prevention) content control and end-to-end encryption.
- **Security Training And 2FA:** Regular [phishing simulations](/phishing-simulation) are _essential to keep employees alert and detect phishing and fraud in emails_. Introducing two-factor authentication (2FA) for the email account is a secure way to add a layer of security to the inbox.
- **API-based Technologies:** It is better to go for API-based solutions rather than using SMTP-based gateways to manage emails via inbound and [outbound SMTP](/email/outbound-smtp) servers. They can provide extra insight and visibility to detect impersonation attacks and BEC better.

## Final Words

> AI-based security models and multi-factor authentication are becoming the norm in the world of email security.

The email security market will grow to **$6.8 billion** by 2025, according to [the Global Email Security Market Research Report](https://www.marketresearchfuture.com/reports/email-security-market-3120). Adopting newer technologies, such as boundary and gateway [email encryption](/email-security/email-security-101-a-brief-guide-on-email-encryption/), client plugins, and cloud solutions is the need of the hour. With the recent announcement by [Microsoft to invest $20 billion in cybersecurity](https://rcpmag.com/articles/2021/08/26/microsoft-20-billion-for-cybersecurity.aspx), other vendors are also compelled to get in the race and look for ideas to improve the same. Organizations need new **email security** approaches that are capable of neutralizing novel and sophisticated attacks. As attackers continue to innovate, security teams must have adaptive [email security](/) technologies that can re-evaluate emails in the light of new evidence.
