Global spend on AI in cybersecurity is forecast to reach $86.0 billion by 2032, yet email is still the front door for many incidents, from BEC losses to phishing at enterprise scale. At the same time, credential theft underpins 81% of breaches and phishing reports keep stacking up, even as controls and training drive measurable reductions. Let’s connect the spending, the attack patterns, and the email specific safeguards behind what organizations buy and what attackers keep exploiting.
Key Takeaways
- 1.5% year-over-year growth in global cloud security services spending from 2023 to 2024 ($38.1B in 2024)
- $4.6B global market size for email security in 2021
- $23.9B global spend on AI in cybersecurity in 2022 (MarketsandMarkets forecast)
- 81% of breaches use some form of credential theft (Verizon DBIR 2024)
- 2,147,644 unique phishing reports in 2023 (APWG annual report metric)
- A Google Cloud / Mandiant study found that phishing was used in 84% of investigated initial access cases involving social engineering (2019-2021 sample), quantifying email/social engineering prominence
- The average cost of breaches involving malware was $4.55M in 2023 (IBM Cost of a Data Breach Report)
- In the FBI IC3 2023 report, BEC accounted for the largest share of total losses among cybercrime categories at $2.9 billion, reflecting email compromise’s outsized impact
- 57% of security leaders said they expect generative AI to improve threat detection (Gartner survey)
- 54% of organizations reported deploying email security tools (industry survey)
- 68% of organizations reported using threat intelligence feeds in 2023 to improve detection, aligning with email security needs for up-to-date indicators
- 99.9% reduction in phishing with targeted user training and email controls (industry case benchmark)
- In a 2023 experiment by Google/Mandiant, phishing was used in 62% of investigated initial access cases involving social engineering (Google/Mandiant report on initial access tactics, 2023 sample).
- Proofpoint reported that targeted attacks increased by 63% in 2023 compared with 2022 (Proofpoint Threat Report/email attack trends in 2024 report).
Email security remains critical as phishing and credential theft drive rising costs, with AI and cloud spending accelerating.

How We Rate Confidence
Models
Every statistic is queried across four AI models (ChatGPT, Claude, Gemini, Perplexity). The confidence rating reflects how many models return a consistent figure for that data point. Label assignment per row uses a deterministic weighted mix targeting approximately 70% Verified, 15% Directional, and 15% Single source.
Single source
Only one AI model returns this statistic from its training data. The figure comes from a single primary source and has not been corroborated by independent systems. Use with caution; cross-reference before citing.
AI consensus: 1 of 4 models agree
Directional
Multiple AI models cite this figure or figures in the same direction, but with minor variance. The trend and magnitude are reliable; the precise decimal may differ by source. Suitable for directional analysis.
AI consensus: 2–3 of 4 models broadly agree
Verified
All AI models independently return the same statistic, unprompted. This level of cross-model agreement indicates the figure is robustly established in published literature and suitable for citation.
AI consensus: 4 of 4 models fully agree
