Voice Firewall

Secure your business with CyberHoot Today!!!

A Voice Firewall logs, monitors, and controls all inbound and outbound voice network activity on a per-call basis through user-defined Call Access Control (CAC) policies. These detailed security and usage policies alert or prevent malicious use of your company voice resources by internal or external callers.

Voice Firewalls help prevent data network exploits over modems, attacks on voice systems and other key infrastructure, unauthorized Internet sessions on phone lines, data leakage, harassing/threatening calls, long-distance abuse, calls to/from restricted parties, and other forms of phone line disruption, misuse, and abuse.

In short, Voice Firewalls can block some inbound calls to your organization that are malicious, like robocalls, spam, and vishing attacks.

What does this mean for an SMB or MSP?

Voice Firewalls are a fairly new technology, but could be beneficial for companies that have problems with malicious phone calls. For most companies, it’s likely not something that will be needed in their security stack. This is particularly true for companies with employees working remotely.

The single best thing that can be done to prevent security issues from malicious phone calls is to train users on avoiding Vishing and Social Engineering attacks so they know what to do if they encounter them. Additionally, following the actions below will help improve your cybersecurity posture significantly.

CyberHoot’s Minimum Essential Cybersecurity Recommendations

The following recommendations will help you and your business stay secure with the various threats you may face on a day-to-day basis. All of the suggestions listed below can be gained by hiring CyberHoot’s vCISO Program development services.

Govern employees with policies and procedures. You need a password policy, an acceptable use policy, an information handling policy, and a written information security program (WISP) at a minimum.

Train employees on how to spot and avoid phishing attacks. Adopt a Learning Management system like CyberHoot to teach employees the skills they need to be more confident, productive, and secure.

Test employees with Phishing attacks to practice. CyberHoot’s Phish testing allows businesses to test employees with believable phishing attacks and put those that fail into remedial phish training.

Deploy critical cybersecurity technology including two-factor authentication on all critical accounts. Enable email SPAM filtering, validate backups, and deploy DNS protection, antivirus, and anti-malware on all your endpoints.

In the modern Work-from-Home era, make sure you’re managing personal devices connecting to your network by validating their security (patching, antivirus, DNS protections) or prohibiting their use entirely.

If you haven’t had a risk assessment by a 3rd party in the last 2 years, you should have one now. Establishing a risk management framework in your organization is critical to addressing your most egregious risks with your finite time and money.

Buy Cyber-Insurance to protect you in a catastrophic failure situation. Cyber-Insurance is no different than Car, Fire, Flood, or Life insurance. It’s there when you need it most.

Each of these recommendations, except cyber-insurance, is built into CyberHoot’s product and virtual Chief Information Security Officer services. With CyberHoot you can govern, train, assess, and test your employees. Visit CyberHoot.com and sign up for our services today.
