Mobile-first social engineering defense
The first phone to see the attack is the last one that has to.
SmishAlert blocks unknown-sender smishing on iOS before anyone taps — on every iPhone, managed or BYOD. The moment any phone in the network reports an attack, it's fingerprinted and auto-blocked on every iPhone. And every attempt we can't block — across Android, WhatsApp, and social DMs — we still capture. All without ever reading an employee's messages.
Blocked on iOS. Captured everywhere.

The gap you can't see
Your email security stops at the inbox. The attackers didn't.
Payroll redirects, executive impersonation, MFA-reset lures, vendor takeovers — the highest-leverage social engineering of the last 24 months is hitting employees in SMS and iMessage first. Your SEG never sees it. Your EDR has no agent there. A personal iPhone on cellular never routes through your gateway.
SmishAlert closes the last mile — not by handing your SOC another queue to triage, but by blocking the attack on the phone before anyone taps. Everything we can't block, we still capture. Nothing is invisible, and everything is on the record.
Prevent · Capture · Prove
Block what we can. Capture what we can't. Prove all of it.
iOS prevention is the point of the spear. Every other channel is the sensor network that makes the blocking smart.
Block the smish before the tap.
iOS · managed and BYOD
Inline blocking of unknown-sender messages on iOS, before they reach the tap. The moment an attack is fingerprinted anywhere — any tenant, any device, any channel — it becomes an automatic block on every iPhone in the network.
- On-device filtering of unknown-sender SMS and iMessage via Apple's Message Filtering extension
- Runs on any iPhone — company-managed or personal (BYOD) — with no MDM required to protect the device
- Cross-tenant intelligence: the first phone to see it is the last one that has to
Nothing gets through invisibly.
Android, WhatsApp, iMessage, social DMs
Where we can't block, employees report suspicious messages in a tap. Those reports don't sit in a queue — they're correlated into named campaigns and they feed the fingerprint database that hardens iOS blocking for everyone.
- One-tap reporting across Android, WhatsApp, iMessage, and social DMs
- Fingerprint-grade correlation clusters lookalike reports into named campaigns
- Report-only is the honest boundary — and the network's early-warning system
An audit-grade record of everything.
SIEM · API · executive readout
Every block and every report becomes a defensible record — executive impersonation, payroll and HR fraud, credential harvesting, vendor impersonation — streamed to your SIEM and available over API.
- Board-ready executive reporting on what was blocked and what was captured
- SIEM/SOAR routing and API access for teams that want signal in their stack
- The system of record beneath prevention — governance, not the headline
Every attack one employee reports makes the whole network safer — automatically.
Where the stack stops
Your defenses stop before the phone. The attackers didn't.
Every layer you already own stops at a boundary the attacker walks right past. The message is the last mile — and it's the one nobody else covers.
What no incumbent can match
Privacy-first and BYOD — together.
We never read anyone's messages.
Classification runs on-device. Only coded fingerprints of unknown-sender messages ever leave the phone — never the content, never a message from a contact. The instant objection to anything on an employee's phone is 'are you reading my texts?' The answer is no. That's what makes deployment on a personal device feasible — and it's a clean one-up on the SWG world, which has to crack open TLS to see anything at all.
On every iPhone — managed and BYOD.
Our app runs on any iPhone, company-managed or personal. That's the exact blind spot EDR, MDM, and the secure web gateway can't reach — and the one Verizon's 2026 DBIR calls a 'risky gap in your visibility.' BYOD coverage isn't a lesser tier. It's the gap the industry's most-cited report is describing.
The network effect
One report anywhere becomes a block everywhere.
Every suspicious message an employee reports — on any channel, in any tenant — is fingerprinted and fed back into the blocking layer. The next time that attack reaches an iPhone in the network, it's stopped before the tap. The more the network sees, the less any single phone has to.
The evidence
What we block on iOS — and capture everywhere else.
The same attack types drive the blocking layer and the audit-grade record beneath it. Here's what a single 30-day window surfaced at one deployment.
Attack types we block and surface
CEO and VIP impersonation in SMS & chat.
Direct deposit and benefits redirect scams.
Fake MFA, IT-help-desk, and login prompts.
Supply-chain messaging compromise.
Multi-channel email, text & voice waves.
Authority & brand spoofs
Bank, IRS, USPS, and SaaS-platform impersonation hitting personal devices.

Read what the DBIR means for your workforce →The SOC promise, corrected
We shrink the queue. We don't grow it.
Roughly 1 in 3 phishing, insider-risk, and DLP alerts go uninvestigated in a given week, and more than 75% of security teams name alert fatigue as a top challenge. Handing the SOC more to look at is the wrong promise. Our auto-block clears the known-bad automatically and only surfaces what's genuinely novel — so your analysts see campaigns, not noise.

FAQ
Questions security leaders ask
How does SmishAlert block smishing before an employee taps?
On iOS, SmishAlert uses Apple's Message Filtering extension to classify unknown-sender SMS and iMessage on-device and block the known-bad before it reaches the tap. The moment an attack is fingerprinted anywhere in the network, it becomes an automatic block on every enrolled iPhone — so the first target is the last target. It runs on any iPhone, managed or personal (BYOD).
Does SmishAlert work on personal (BYOD) iPhones?
Yes. SmishAlert's iOS filtering runs on any iPhone — company-managed or personal — with no MDM required to protect the device. That's the exact blind spot EDR, MDM, and the secure web gateway can't reach, and the one Verizon's 2026 DBIR calls a 'risky gap in your visibility.' For assessment-grade measurement across a fleet, the pilot runs in Workforce mode on managed devices.
Does SmishAlert read employees' messages?
No. Classification runs on-device, and only coded fingerprints of unknown-sender messages ever leave the phone — never the content, and never a message from a contact. That privacy-first posture is what makes deployment on a personal device feasible, and it's a clean one-up on secure web gateways, which have to decrypt TLS to see anything at all.
How do I measure my workforce's exposure to social engineering?
Book a scoping call and run the SmishAlert 30-day exposure pilot. We deploy our app to 25–100 of your employees, block the known-bad on iOS, capture every attempt we can't block, correlate reports into named campaigns, and end with an executive-grade findings report your CEO and board will read. $2,500 for up to 50 users, credited toward an annual subscription if you move forward.
What's the difference between SmishAlert and a secure email gateway (SEG)?
Your SEG stops at the inbox. SmishAlert blocks the attack on the phone — in SMS, iMessage, and chat — before anyone taps, and keeps an audit-grade record of everything it can't block. We don't replace your email security; we cover the messaging-channel attack surface it was never built to see, which is now where the highest-leverage attacks land first.
What does the SmishAlert 30-day exposure pilot include?
Deployment of the SmishAlert mobile app across 25–100 enrolled users, a reporting portal with classified and correlated message data, a 60-minute executive readout call, a written findings report (branded for your leadership team), and a vertical-specific threat intelligence summary. Pricing is $2,500 for up to 50 users or $5,000 for 51–100 users.
Can SmishAlert deploy across a managed iOS and Android fleet via MDM?
Yes. SmishAlert ships native apps for iOS and Android, both MDM-deployable via Jamf, Addigy, Intune, or any provider that supports iOS Message Filtering extensions and Android Enterprise. On iOS we capture every unknown SMS / iMessage via the Message Filter extension; on Android employees report into the same Workforce-mode dashboard via Share Sheet, in-app, and screenshot upload (filter parity on Android tracks platform APIs). The pilot lands cleanly across a 25–100-user MDM-pushed deployment in a single week.
How is the pilot fee credited toward a subscription?
100% of the pilot fee is credited toward your first year of an annual SmishAlert subscription if you move forward after the executive readout. Subscription pricing is scoped during the readout — typical deployments are $4.99–$7.99 per user per month annual. The $1,500 monthly minimum ensures dedicated analyst support, threat intelligence, and executive reporting for every account.
Who is SmishAlert built for?
Security leaders at 200–2,500-employee organizations in healthcare, financial services, professional services, and HR/payroll — verticals where impersonation, payroll fraud, and credential harvesting cost real money and where the buyer needs a defensible number for the board.
