Summer travel has always created security challenges for businesses. People leave the controlled office environment and carry on working from airports, hotels, trains, cafes, rental homes, conference venues and international networks.
That is normal now – The problem is that the mobile phone has become the center of both work and travel.
It is the boarding pass.
The hotel key.
The corporate inbox.
The Microsoft Authenticator app.
The payment method.
The banking app.
The Teams and WhatsApp device.
The camera for scanning QR codes (and taking holiday snaps).
The route planner.
The device people reach for when something feels urgent.
That makes mobile one of the most important attack surfaces in the business and travel is often when that attack surface is most exposed.
Why travel increases mobile risk
When people are travelling, they behave differently. They are moving quickly. They are distracted. They are using unfamiliar Wi-Fi. They are scanning QR codes. They are installing apps they would not normally install. They are reacting to travel updates, payment alerts, delivery messages, booking confirmations and “urgent” security prompts.
That is exactly the kind of situation attackers exploit.
A mobile attacks are not always complex – sometimes they starts with a simple message:
“Your flight has changed.”
“Your toll payment failed.”
“Your hotel booking needs confirming.”
“Your parcel could not be delivered.”
“Scan this QR code to connect to Wi-Fi.”
“Open this PDF receipt.”
“Verify your account now.”
On a laptop, some of these threats may be filtered, inspected or blocked by existing business controls. On a mobile device, especially one used for both work and personal activity, the business may have far less visibility.
Public Wi-Fi is still a problem
Public Wi-Fi has been a known risk for years. When employees connect to open or unfamiliar networks, they may expose themselves to rogue access points, malicious captive portals, traffic interception or redirects to fake login pages.
Mobile security protection is designed to help prevent man-in-the-middle attacks and protect against threats across apps, files, network and operating system layers.
Mobile threats can come through the network, the app, the browser, the operating system, a file download or a phishing link.
Mobile phishing follows people wherever they go
Travel creates urgency and urgency creates clicks. That is why mobile phishing is so effective.
A person waiting at an airport is more likely to tap a text message about a delayed flight. Someone checking into a hotel may be more likely to trust a Wi-Fi portal. Someone abroad may be more worried by a banking alert or roaming charge.
Zimperium’s 2025 Global Mobile Threat Report says mobile-targeted phishing, often called “mishing”, represents roughly one-third of threats identified by zLabs. It also reports that smishing, or SMS and messaging-based phishing, makes up more than two-thirds of those mishing attacks.
Mobile phishing can arrive through:
SMS
WhatsApp
iMessage
QR codes
social media messages
fake Wi-Fi portals
malicious PDF attachments
personal email
collaboration apps
That makes it harder for traditional email security alone to catch.
Personal apps can create business risk
Travel also encourages people to install apps quickly.
Parking apps.
Transport apps.
Local taxi apps.
Translation apps.
Event apps.
Airline apps.
Hotel apps.
Payment apps.
Most of these are not reviewed by the business before they are installed.
That matters when the same device is also used for corporate email, MFA, Microsoft 365, file access and client communication.
Zscaler ThreatLabz reported a 67% year-on-year rise in Android malware transactions in its 2025 mobile threat research, with banking trojans and spyware continuing to be a major concern.
These threats often disguise themselves as useful or familiar apps. Some aim for banking fraud. Others steal credentials, intercept codes, abuse accessibility permissions or gather sensitive data.
The problem for businesses is simple. The app may look personal. The risk may not be.
If a malicious app lands on a device that also holds business email, MFA tokens, Teams access or client data, it can become a business security issue very quickly.
Why mobile security needs to be part of business cyber security
Many businesses have improved laptop security. They may have antivirus, endpoint detection, Microsoft 365 security, email filtering, backups, MFA and patching. But mobile devices are often treated differently.
That gap is getting harder to justify.
For many employees, the phone is now the front door to the business.
It receives MFA prompts.
It stores email.
It accesses cloud files.
It handles Teams and chat.
It contains business contacts.
It opens attachments.
It scans QR codes.
It connects from networks the business does not control.
If that device is compromised, the business may not know until damage has already been done.
How Check Point Harmony Mobile helps
Check Point Harmony Mobile, now also referred to as Check Point Mobile Security, is designed to protect mobile devices across the main mobile attack routes: apps, files, network and operating system threats.
It can help businesses protect against:
mobile phishing
malicious apps
malicious file downloads
risky Wi-Fi and network attacks
man-in-the-middle attacks
operating system vulnerabilities
rooted or jailbroken devices
compromised devices accessing corporate resources
Check Point’ Mobile Security can block phishing attacks across apps such as email, messaging and social media, as well as help prevent man-in-the-middle attacks on Wi-Fi and cellular networks.
Mobile protection should not only look at corporate email – It needs to look at the wider mobile behaviour that creates risk.
What businesses should do before peak travel season
Summer travel is a good moment to review mobile security. Before staff start travelling, businesses should ask:
Do we know which mobile devices access company data?
Can we detect mobile phishing outside corporate email?
Can we spot risky or malicious apps?
Can we block access from compromised devices?
Do we know when a device is rooted, jailbroken or vulnerable?
Do we have controls for public Wi-Fi and man-in-the-middle attacks?
Do we protect mobile devices used for MFA and Microsoft 365 access?
If the answer is “not really”, mobile security should be on the roadmap.
Mobile is not separate from cyber security anymore
Mobile devices are now part of identity, communication, payments, travel and work and attackers know this.
They also know that people are easier to trick when they are tired, rushed, distracted or trying to solve a travel problem quickly.
That is why mobile security is important.
Protecting laptops and email is also important, but it is not enough.
If your team can access business systems from a mobile device, that device needs protection too.
Summer travel will end.
The mobile risk will not.
Black Swan Cyber Security Solutions can help you review your mobile security risk and assess whether Check Point Harmony Mobile is the right fit for your organisation.
