Summer cyberthreats: How to protect your business during vacation season

Cybercriminals don’t take summer vacations — in fact, it’s their prime hunting season. While you’re trying to disconnect, they’re counting on skeleton crews and relaxed remote work protocols to create the perfect opportunity to strike.

Consider the stakes: statistics show that one in three small and medium-sized businesses (SMBs) have experienced a successful cyberattack. Fortunately, a proactive security plan can protect your business and preserve your peace of mind, ensuring that when you unplug, your assets stay secure.

Why cyberattacks spike in the summer

Attackers are opportunistic, and they know that summer operations create predictable vulnerabilities they can exploit.

Reduced on-site staff

With key personnel, including IT staff, on vacation, incident response times are naturally slower. An alert that might be addressed in minutes on a normal Tuesday could go unnoticed for hours or even days, giving attackers a critical window to escalate their access and do more damage.

The “vacation brain” effect

Employees (and even managers) are often more distracted and less vigilant before, during, and after a vacation. This lapse in focus makes them more susceptible to social engineering, as they might quickly click a malicious link in a “flight update” email without a second thought.

Reliance on insecure networks and personal devices

Summer travel means employees are more likely to connect from hotel, airport, or cafe Wi-Fi. These public networks are often unencrypted and rife with risk, allowing attackers to intercept data. Additionally, an employee checking email on a personal laptop or phone that isn’t managed by company IT can unknowingly introduce a threat, as these devices may lack critical security updates and software.

With fewer eyes on the network, who is watching for threats? This is where having a partner that provides proactive, 24/7 monitoring and support becomes critical for business continuity.

Top summer cyberthreats targeting your business

While threats are numerous, two specific risks become much more potent during the summer months. Understanding them is the first step toward building an effective defense.

Seasonal phishing and social engineering scams

Phishing attacks aren’t new, but criminals tailor their lures to the season to increase their success rate. Summer-themed scams prey on the activities and mindset of your employees. Some common examples include emails with malicious links disguised as:

  • Fake flight confirmations or cancellation notices
  • Sudden issues with hotel bookings
  • Package delivery issues for online orders
  • Urgent payment requests from a “vacationing” CEO or executive

The shift to remote and hybrid work has already made these threats more dangerous, and summer inflates the risk. When colleagues are on vacation, that quick “does this look real to you?” check is impossible. A moment of pre-vacation distraction is all an attacker needs to turn a clever seasonal scam into a major security breach — a reminder that your human firewall is your most critical line of defense, especially during the summer months.

Remote work risks

The flexibility to work from a vacation rental or extend a trip is a great perk, but it introduces significant security risks. Outside the protected office network, employees may inadvertently expose company data through:

  • Unsecured public Wi-Fi: Wi-Fi networks in public places are rarely encrypted or password protected.
  • Personal devices: An employee’s personal laptop or phone may lack the security software and policies of a company-managed device.
  • Lax security practices: Outside the formal office environment, employees may be less cautious about locking their screens or may be more susceptible to shoulder surfing.

A formal remote work security policy is therefore crucial for mitigating these risks. It should clearly outline expectations for data protection, device security, and acceptable online behavior so that employees understand their responsibilities regardless of where they’re working from.

Your proactive summer cybersecurity checklist

Effective security is all about building a defense in depth. A layered IT security strategy integrates people, processes, and technology to protect your business from every angle. Use this checklist to review your defenses before vacation season.

uncheckedAutomate patch management
Configure systems to automatically update all operating systems and software to patch critical vulnerabilities.
Closes known security gaps before criminals can exploit them
ProcessuncheckedEstablish a clear remote work policy
Define rules for using public Wi-Fi (e.g., must use a VPN), accessing company data, and reporting lost/stolen devices.
Removes ambiguity and sets clear security expectations for employees working from anywhere
uncheckedImplement the principle of least privilege
Give employees access to only the data and systems they need to do their jobs.
Limits the potential damage an attacker can do if an employee’s account is compromised
uncheckedTest your backups and incident response plan
Before vacation season starts, verify that your data backups are working and that your incident response plan is up to date.
Ensures you can recover quickly from an attack, minimizing downtime even with key staff away
PeopleuncheckedConduct pre-summer security training
Run a brief training session focused specifically on seasonal phishing scams and remote work cybersecurity best practices.
Reinforces cybersecurity awareness and puts security top of mind before the vacation mindset kicks in
