The Mobile Phishing Visibility Gap

Why SMS and voice attacks bypass enterprise reporting, and where security teams lose visibility.

Organizations spent the past decade building phishing visibility for email. Gateways, report buttons and security team workflows all sit on that one channel. Attackers moved on. In the 2026 Verizon Data Breach Investigations Report, phone-centric simulations show a median click rate of around 2 percent against roughly 1.4 percent for email, and phone-based failure runs about 40 percent higher (Verizon, 2026 Data Breach Investigations Report, p. 50). The reporting workflows that would catch those attempts never followed them out of the inbox.

What the whitepaper covers

Three findings shape the paper.

Reporting maturity has not extended to mobile communication channels. A phone call has no report button the way email does, so security teams usually learn about an SMS or voice attack only after the incident has progressed.

Security team visibility drops sharply outside email workflows. The controls organizations invested in for email have no equivalent layer for SMS, voice or other personal channels.

A report is only useful once it becomes an analysed signal. The gap is between report and response, not between awareness and ignorance.

The numbers behind the gap

Phone-centric simulations show a median click rate of around 2 percent against roughly 1.4 percent for email, with phone-based failure about 40 percent higher (Verizon, 2026 Data Breach Investigations Report, p. 50).

80 percent of organizations experienced mobile phishing attempts (Verizon Business, 2025 Mobile Security Index).

Smishing volume grew 30 to 40 percent quarter over quarter through 2025 (Anti-Phishing Working Group, Phishing Activity Trends Report, Q4 2025, p. 4).

The human element appeared in 62 percent of breaches (Verizon, 2026 Data Breach Investigations Report, p. 12).

Who should read this

Security leaders who already run a mature email phishing program and want to know what the next channel costs them. Security operations teams that receive reported email but have no equivalent pipeline for SMS and voice. Risk and compliance teams that need to measure a reporting rate across every channel, not just one.

Questions the whitepaper helps you answer

Can employees report suspicious SMS messages centrally.

Do security teams receive an analysed verdict, or only a raw report.

Are voice phishing incidents tracked as operational events.

Do mobile phishing workflows exist outside email at all.

Can you measure an SMS and voice reporting rate the way you measure it for email.
