Email Security Market Analysis
The Email Security Market size is estimated at USD 5.23 billion in 2025, and is expected to reach USD 9.55 billion by 2030, at a CAGR of 12.78% during the forecast period (2025-2030).
- Email security remains paramount for both individuals and organizations, especially as cyber threats grow more sophisticated. Spear phishing, a targeted form of phishing, has become both more frequent and more advanced. Attackers now craft emails that impersonate trusted entities—be it colleagues, vendors, or friends—deceiving recipients into revealing sensitive information or taking harmful actions.
- Hackers have recently adopted a new tactic: using QR codes for phishing, a method dubbed 'Quishing'. Here, malicious links or files are hidden within QR codes. This allows attackers to bypass traditional email filters, which often lack the capability to detect or read QR codes. Unlike standard phishing emails that display links or attachments, QR code phishing poses a unique challenge, making it harder for users to recognize and address the threat.
- According to MX Layer, June 2023 saw 5,063 reported cases of QR code phishing. Of these, only 36% were correctly identified and reported. The energy sector emerged as the most susceptible, accounting for 29% of over 1,000 malware-laden phishing email QR codes.
- Data breaches via compromised email accounts account for a significant 30%, highlighting the urgency of email system security. Such breaches can cost organizations over USD 3 million on average, considering lost revenue, recovery expenses, and damage to reputation. This underscores the widespread adoption of email security solutions.
- The ongoing Russia-Ukraine conflict has spurred a rise in cyber attacks, showcasing how global conflicts can be exploited by threat actors. In August 2024, Ukrainian authorities alerted to a malware campaign targeting government entities. The campaign used emails mimicking the Ukrainian Security Service. CERT-UA, Ukraine's Computer Emergency Response Team, noted that these malicious emails were widely disseminated by attackers challenging the Security Service. They've identified over 100 compromised systems, mainly within central and local government bodies in Ukraine, indicating significant market growth.
- Managing email security protocols can become complex with the integration of multiple security tools. Organizations often struggle to balance streamlined security settings with robust protection against varied threats, potentially stunting market growth.
- Post-COVID, the email security landscape has transformed, fueled by a heightened dependence on digital communication and the emergence of advanced cyber threats. With the growing use of mobile devices for email access, especially over unsecured networks, the risk exposure amplifies. This trend underscores the need for strong mobile security measures in addition to conventional email safeguards.
Email Security Market Trends
Cloud to Hold Significant Market Growth
- The rise of the digital landscape has underscored the importance of email as a key communication tool. However, this widespread use also renders email systems vulnerable to cyberattacks. Integrated Cloud Email Security solutions have been developed to combat these threats with advanced protective measures. The core focus of Integrated Cloud Email Security solutions is to emphasize their features, benefits, and how they stand apart from traditional solutions like secure email gateways (SEGs).
- As companies ramp up their digital transformation efforts, there's a clear pivot towards cloud-based infrastructures. With a growing number of businesses transitioning to platforms such as Google Workspace and Microsoft 365, the appetite for integrated cloud-native security solutions has intensified. Unlike traditional on-premises systems, cloud-based email security solutions are more cost-effective, thanks to diminished infrastructure and maintenance demands, coupled with rapid deployment and updates. In today's fast-paced work environment, secure cloud email services are crucial for smooth collaboration and communication.
- Furthermore, in February 2024, Mimecast, an AI-driven Email Security solution provider, highlighted that in Q4 2023, spamming, phishing, and malware were the predominant email threats globally, underscoring the rising demand for cloud-based email security solutions.
- Collaborations between cloud-based email security solutions and public cloud services are poised to propel the market forward. In July 2024, Barracuda Networks, Inc., a trusted name in cloud-first security solutions, including email security, forged a Strategic Collaboration Agreement (SCA) with Amazon Web Services (AWS). This partnership aims to provide Barracuda's clientele with enhanced flexibility and ease in licensing, procurement, and deployment.
- Moreover, the increasing use of connected devices is exposing vulnerabilities in IT infrastructures at end-user locations, driving up the demand for cloud-based email security, especially due to their scalability. For example, in January 2024, Egress Software Technologies, a provider of cloud-based email security solutions, noted that email security was a top priority for cybersecurity professionals in 2023, with over 90% of cyber decision-makers facing phishing attacks, highlighting the market's growth potential.
North America is Expected to Hold a Major Share of the Market
- The North American email security market is booming, fueled by a surge in cyber threats and the transition to remote work. The uptick in malware and phishing incidents, especially ransomware and targeted attacks like Business Email Compromise (BEC), has spurred a heightened demand for email security solutions.
- According to Forbes, Business Email Compromise (BEC) led to losses surpassing USD 2.9 billion in the U.S. in 2023, highlighting the financial imperatives of safeguarding email communications.
- Organizations are increasingly turning to cloud-based email security solutions to bolster their defenses in the era of remote work. This trend is driven by the need for adaptable and scalable security measures. Public cloud-based email security, managed by third-party giants like AWS, Google Cloud, and Microsoft Azure, offers businesses subscription-based access to services. These services come equipped with features like advanced threat protection, data loss prevention, encryption, and compliance reporting.
- In the U.S., there's a pronounced emphasis on email security across public, private, and government sectors. For example, in May 2024, the FBI's San Francisco division cautioned individuals and businesses about the rising threats from cybercriminals leveraging artificial intelligence (AI) for advanced phishing and social engineering attacks. The FBI's recommendation for businesses to adopt technical solutions to mitigate phishing risks bodes well for the market's future growth.
- Regional vendors are now providing organizations with comprehensive strategies to ensure timely detection of all potential threats. In May 2024, Proofpoint, Inc. unveiled a comprehensive end-to-end email protection solution, fortifying the entire email delivery process. Their enhanced core email security suite, featuring The Proofpoint Adaptive Email Security and the Integrated Cloud Email Security (ICES) solution, integrates pre-delivery, click-time, and post-delivery detections. Notably, the ICES tool harnesses behavioral AI for advanced threat detection. These developments underscore the surging demand for email security in the region.
