Why you need a VPN and how to choose the right one

Posted on November 8, 2021 by Joseph Voldeck

Today, just installing anti-malware software and a firewall on your computer isn’t enough to keep you safe as you use the internet. Nowadays, a hacker can intercept messages sent to and from your computer and steal the data they contain. This is why you need a virtual private network (VPN).

What is a VPN?

A VPN creates a secure tunnel between your device and the websites you visit, protecting you from hackers looking to intercept your data. All data transmitted and received through this secure connection is encrypted, preventing any third party from monitoring your online activities.

VPNs can also disguise your location. Once you’ve established a connection to a VPN server, your computer acts as if it’s using the same local connection as the VPN. As far as websites are concerned, you are browsing from the server’s geographical area and not your actual location.

Why should you have a VPN?

VPNs augment your cybersecurity and help protect your privacy. For instance, it’s generally considered bad practice to connect to public Wi-Fi networks, like those in cafes, libraries, and airports. This is because all data transmitted through these networks are unencrypted and, thus, are susceptible to exposure and theft. If you must use public Wi-Fi, make sure to activate your VPN. The VPN encrypts your data and keeps your connection secure as you surf the internet.

VPNs’ ability to mask your location also makes them ideal for accessing geo-restricted websites and content. If you’re traveling abroad and you find that critical documents or US websites are geo-blocked in your current location, just connect to a VPN server in the United States to regain access.

How do you choose a VPN?

Given the increasing demand for greater online privacy, VPNs are surging in popularity. When selecting which VPN to purchase, take the following into account:

Cost

There are free VPNs out there, but they likely keep logs of your internet activity or are filled with disruptive ads. That’s why it’s best to invest in paid VPNs like NordVPN and ExpressVPN. These paid options come with robust features, such as a large list of available servers, and configurations that bolster your data’s security.

Location

Where your VPN’s servers are located matters for several reasons. For one, the farther away the server you’re connected to is, the greater the likelihood that you’ll suffer latency issues. For a smooth surfing experience, it’s best to connect to the closest available server. Additionally, if you want to avoid geo-restrictions, you’d want to connect to servers in the same location as the content you’re looking to access. This means if you want to access research published in the United Kingdom, make sure your VPN has servers located in that country.

Capacity

Inquire with the provider or read their terms of service to determine how much data you’re allowed to use. If your tasks require a lot of online resources, then you should choose a VPN with a high data allocation. Also, find out how many of the VPN servers are online; a greater number of online servers means the VPN is capable of supporting resource-intensive tasks

Device compatibility

Choose a VPN that can be used across multiple devices. If you use your laptop, tablet, or smartphone to do your tasks, then you should invest in a VPN that’s compatible with all of these.

IP leak

Some VPN tunnels are not as secure as others. In some cases, the VPN could leak your IP address, enabling third parties to track your data and activities. Before buying a VPN, sign up for a free trial of the service if available. Activate the VPN and visit IP Leak. If the website says your IP address is being leaked, choose a different VPN.

5 Vital VoIP measures to implement

Posted on November 2, 2021 by Joseph Voldeck

Voice over Internet Protocol (VoIP) technology is a flexible, scalable, and highly efficient communication solution that more and more modern businesses are relying on. However, a large user base makes VoIP an attractive cybercrime target, which means VoIP users face increasing risks. Here are five effective security measures you can implement to protect your business’s VoIP systems and devices from various threats.

24/7 monitoring

VoIP security breaches usually take place outside operating hours. Attackers make phone calls using private accounts or access call records with confidential information on the sly. To avoid these security breaches, contract outsourced IT vendors to monitor network traffic for any abnormalities.

Virtual private networks

Virtual private networks (VPNs) create a secure connection between two points, as if they belong in the same closed network. It’s like building a safe secret tunnel between you and the person you’re calling. Using a VPN can also help overcome complications involving Session Initiation Protocol or SIP trunking, which is a recommended VoIP feature.

VoIP firewalls

Firewalls specifically designed for IP-based telephony curb the types of traffic that are allowed into your network. They ensure that every connection is properly terminated at the end of a session and identify suspicious calling patterns. Virtually every VoIP vendor provides these protocols, but you should always consult with your IT services provider as to how these protocols will be managed within your organization.

Encryption tools

VoIP systems that lack encryption can be easily broken into by hackers — even by amateur ones who can simply download and deploy tools to eavesdrop or intercept your calls. Some services claim to have built-in encryption, but companies still need to be vigilant and investigate how effective these are.

Using encryption ensures that even if hackers successfully download audio or video, they still won’t be able to decode the file unless they have the decryption key.

Password protection

Using passwords to authenticate your access to private information is not as secure as it once was. Hackers can easily guess a password and use it for cyberattacks. Protecting the passwords themselves adds a layer of protection against threats. This can entail enabling multifactor authentication or using a password manager to generate and store an array of complex passwords.

VoIP is as important as any of your other network security considerations. It requires a unique combination of protection measures, and we’d love to give you advice on these. Give us a call today to get started.

Tips to keep your business data safe

Posted on July 14, 2021 by Joseph Voldeck

Losing or compromising data can be disastrous for your business. It can lead to reputational damage, costly lawsuits, and termination of contracts, among others. And because threats to data security are always present online, it’s important to implement tough security measures that will keep your business data safe 24/7. Here are some tried-and-tested methods to safeguard your corporate data.

Use two-factor authentication

Using a complicated password to secure your system is not an effective way to level up your cybersecurity. That’s because having to memorize a difficult password often pushes users to set that same complex password for multiple accounts. And if a hacker gets a hold of a recycled password, there’s a high probability that they could access all your accounts that use that same password.

Two-factor authentication (2FA) adds an extra layer of security to your systems and accounts. 2FA comes in many forms: it can be a biometric verification in the devices that you own or a time-sensitive auto-generated code sent to your mobile phone. This security feature works similarly to how websites would require you to confirm your email address to ensure that you are not a bot.

Encrypt all data

Encryption is an effective obstruction to hackers, since it scrambles and descrambles data every time someone tries to read it. Encryption also causes compatibility issues if the data is not being accessed via a company’s own network systems. While applying encryption can be expensive, it is certainly well worth the money because it protects your data in case it falls into the wrong hands.

Keep systems up to date

Hackers are always upgrading their tools to take advantage of outdated security systems, so companies should keep up to protect their valuable technology resources. Many companies don’t install software updates immediately, and that’s a huge problem. Updates often close existing security loopholes, which is why delayed installation can mean exposing your systems to external attacks. Keep your data safe by installing software updates as soon as they are released.

Back up frequently

Implementing several layers to your security doesn’t ensure that hackers won’t find their way into your systems. This is why you need to back up data frequently, whether it’s on-site, off-site, or by way of cloud backups. In the worst-case scenario where your systems do get infiltrated, you can restore lost data from your backups.

Monitor connectivity

Many businesses have no idea how many of their devices are connected online at a given time, so it’s very hard for them to keep track of which of these should actually be online. Sometimes, a company’s computers and servers are online when they don’t need to be, making these tempting and easy targets for attackers. It’s advisable to configure business servers properly to guarantee that only necessary machines are online and that they’re well-protected at all times.

It’s much more expensive to recover from a data breach than to prevent one. If you’re looking to protect your business IT systems from potential threats, contact us today so we can help.

Better internet security: Easy as 1, 2, 3

Posted on February 3, 2021 by Joseph Voldeck

The internet is not such a bad place to be in — for as long as website owners do their share in keeping it safe for their visitors. Here are three tips to do exactly just that.

Tip 1: Use HTTPS

Short for Hypertext Transfer Protocol Secure, HTTPS indicates that a website has an extra layer of security for its users. This layer encrypts data exchanged between a user’s browser and the web server that delivers the data requested by the user. To use a simpler comparison, imagine someone tapping your landline, but instead of getting to listen in on your conversations, they’ll hear people speaking in tongues instead.

In August 2014, Google Chrome, the world’s most popular browser, announced that having HTTPS makes your website rank higher in its search algorithm. And since October 2017, the browser began flagging non-HTTPS websites as not secure whenever users try to fill out something as simple as a contact form on it. In July 2018, Chrome started showing a “not secure” warning on any website that does not implement HTTPS, whether or not users are filling out a form there.

Because of Google’s measures, the security protocol has been widely adopted. Even if your website does not contain or ask for sensitive information, implementing HTTPS engenders trust and a sense of security among internet users, while remaining on HTTP will make web visitors abandon or avoid you sooner or later.

Tip 2: Embrace multifactor authentication (MFA)

Since account credentials can be easily stolen via phishing attacks, username and password combos are no longer enough to keep bad actors at bay. To ensure that the one accessing an account is truly that account’s owner, additional identity authentication steps must be implemented.

These steps can involve the use of the account holder’s device — the one logging in must first verify their phone number, receive a one-time password on their smartphone, then enter that code in the access portal before the code’s validity lapses. Alternatively, MFA may ask for a face, retina, voice, or fingerprint scan for authentication.

MFA can be a bit of a hassle for your internal and external users, but a little inconvenience is a small price to pay for immensely effective cybersecurity.

Tip 3: Update browsers and devices

Did you know that dated versions of browsers, operating systems, and even other software packages can create an easy entry point for hackers? Often, new updates are created specifically to fix security holes. However, people tend to procrastinate and leave applying updates for another day. Hackers take advantage of this by searching for outdated devices to infiltrate while their victims watch YouTube on last year’s version of Firefox.

Yes, installing an update might take 15 minutes of your time, but this time investment can pay dividends in terms of preventing a security breach that could cost you or your business thousands.
