Cybersecurity has never been more critical—especially for small and mid-sized businesses in growing communities like Portsmouth, NH.
In 2025, cybercriminals aren’t just targeting large corporations. Local businesses—from law firms and healthcare providers to retail shops and manufacturers—are now firmly in the crosshairs. That’s why Axis Computer Networks is working with Portsmouth businesses to stay ahead of the curve and build strong, proactive IT defenses.
Here’s a closer look at the top cybersecurity threats facing Portsmouth businesses in 2025, and what you can do to protect yourself.
1. AI-Powered Phishing Attacks
Gone are the days of poorly written scam emails. In 2025, phishing attempts are powered by artificial intelligence, making them highly personalized and incredibly difficult to detect. These emails often mimic real clients, vendors, or even internal staff.
Red flags to watch for:
- Slightly misspelled domains
- Urgent requests to download attachments or change payment info
- Unexpected messages with links that require login credentials
2. Ransomware-as-a-Service (RaaS)
Ransomware is now a booming underground industry. With RaaS, even low-skilled hackers can deploy advanced malware by renting ransomware kits on the dark web. Once your systems are locked, you may be asked to pay a massive fee in cryptocurrency to regain access.
Prevention tips:
- Frequent backups stored offsite
- Endpoint protection software
- Network segmentation and multi-factor authentication
3. Insider Threats
Whether intentional or accidental, employees are one of the biggest security risks. This is especially true with more remote access, use of personal devices, and decentralized systems.
Ways to reduce risk:
- Set user permissions carefully
- Conduct regular security awareness training
- Monitor network activity in real-time
4. Deepfake and Voice Cloning Scams
New tech brings new scams. Deepfakes and AI-generated voice cloning are being used to impersonate business leaders and trick employees into authorizing financial transactions.
Stay alert by:
- Verifying unusual requests by phone or in person
- Creating internal processes for financial approvals
- Using code words for sensitive transactions
5. Outdated Infrastructure
Legacy systems may still run your business, but they’re also full of vulnerabilities. Outdated firewalls, unsupported software, and aging servers are easy targets for hackers.
The solution?
Regular audits and proactive upgrades—not just for convenience, but for security.
