We see the endpoint—that includes every laptop, desktop, server, mobile device, and IoT gadget connected to your network—as the front line of your defense. Failing to secure every single one of these points is not just a risk; it's an invitation. You need to identify all the endpoints on your network and work to secure them. Here’s why, and how.

From the classic Nigerian Prince emails to the cleverly crafted fake invoice, malicious digital correspondence is a constant, evolving threat to any business. It's not just about losing a few dollars, either. A successful phishing attack can cripple your operations, compromise sensitive data, and even lead to devastating financial and reputational damage.

Technology unlocks incredible potential, but is also constantly stalked by an increasingly sophisticated adversary: cybercrime. For businesses of all sizes, threats are changing faster than ever, driven by new technologies and a highly organized criminal industry.

To protect your profits, reputation, and continuity, your business can no longer rely on yesterday’s defenses. You need to understand the evolution of the threat and implement a proactive, multi-layered strategy.

When you send someone within your business an email, the expectation is that they will read it and respond accordingly. Unfortunately, messages can sometimes slip through the cracks, especially for small businesses with limited staff and an impossible workload to keep up with. If you primarily use email to communicate with your team, you need an email archiving system that can help ensure lost emails aren’t setting your business up for disaster.

Passwords are an important part of ensuring your IT infrastructure remains safe, but they are far from the most effective security solution. It’s not necessarily the fault of the password, either; it’s just that hackers and scammers have gotten a lot better at cracking passwords in recent years, even reasonably complex ones. We recommend you implement multi-factor authentication as a secondary precaution against breaches—and here’s why.

How much would you be willing to pay to keep all of your business’ records from being locked away, or to keep them off the dark web? Hundreds? Thousands? More?

This is precisely what cybercriminals rely on when they infect businesses just like yours with ransomware. Let’s talk about ransomware a bit: what it is, why it’s so effective, and (most importantly) how to keep it from dragging your business down.

Here’s a fun thought experiment; can your team identify phishing scams and respond to them appropriately? It’s a skill that must be learned if you want your organization to be successful and safe. Today, we’re taking a look at the three big signs you’re looking at a phishing scam (and what to do about it).

Ransomware seems to be everywhere. One can hardly turn on the news without hearing about a new ransomware attack—and that’s just the ones that hit the news cycle, not to mention the smaller ones that are either hidden by the companies or not considered newsworthy. Meanwhile, businesses are urged to invest in more security tools and IT-themed acronyms than ever. Is all this investment actually worth it? Is ransomware actually as significant a threat as it is made out to be?

The truth is, it isn’t. If anything, it’s even worse.

Every business relies on vendors for a lot: software, services, you name it. They’re a huge part of our businesses’ ability to meet the market’s demands. The way business is done today, in order for them to do their job, they often need access to our data; but, just like you wouldn’t hand over your house keys to a stranger, you shouldn’t just hand over the keys to your data to every vendor without a second thought. When you give vendors broad, indiscriminate access, you're opening the door to some seriously bad situations.

The more IT you use, the more conscientious you have to be to ensure that an action you—or your staff—takes doesn’t unwittingly put your business at risk. Today, we’ll go through some ways for you to do your best to stay secure. Let’s get started.

You know that friend that is still rocking a cracked iPhone 6? It works, but it's slow, the battery dies in two hours, and it can't run the latest apps. Now, imagine a whole company doing that, but with every piece of their tech. That's a recipe for disaster.

You want to make network security one of your top priorities, especially these days when you can hardly go online without feeling like someone’s trying to take advantage of you. The password still plays a dominant role in network security, but the fact remains that it’s only one credential that hackers need to target you. Instead of depending on the password, more businesses are shifting to two-factor authentication, or 2FA.

Scams are often so convincing that it’s difficult for even experienced individuals to detect them, but why is this the case? It all boils down to human psychology. Modern security training can help you identify these telltale signs, but it doesn’t really explain the why of things. That’s what we’re out to explore today.

Ransomware is bad, and you can’t take any chances with it if you want to keep your business safe. Understand that it might seem like we’re exaggerating, but we’re not; ransomware really is as bad as it comes, and when you’re faced with double or even triple extortion, you’ll be put in a tough spot that no business owner wants to find themselves in. Today, we want to cover what these terms are and why they’re so bad.

You've heard the saying, "A man's home is his castle." When it comes to your business, that comparison is even more fitting. Your business is your livelihood, your stronghold, and it deserves the strongest defenses.

Just like a medieval castle was built to keep threats out, your business' security needs to have an all-encompassing strategy. That’s why it is absolutely necessary to implement cybersecurity measures that serve the same protective purpose for your business and its network.

Unfortunately, not every message that lands in your inbox has your best interests at heart. Malicious actors are casting wider and more sophisticated nets than ever before, hoping to reel in an unsuspecting employee and gain access to your business' valuable data and finances. Fear not, with a little knowledge and a healthy dose of skepticism, you can learn to spot these email scams and keep your organization safe.

From your fridge to your fitness tracker, manufacturers are constantly adding smart features. While that can be super convenient, it also opens up a whole can of worms when it comes to your privacy. Sometimes, companies aren't doing enough to keep your data safe, or worse yet, they're actively trying to exploit it. Let's discuss how smart devices might be secretly undermining your family's (and your business') privacy.

Happy Social Media Day! It’s hard to believe that social media—at least in the modern sense—has already been around for almost a quarter-century. Seriously! LinkedIn launched in 2003, and Facebook launched in 2004.

Since then, social media has become an essential business tool; however, it also provides cybercriminals with an opportunity to exploit your organization. Let’s observe Social Media Day by reviewing some simple security line items to keep your business safe while you take advantage of the capabilities social media can provide.

Mobile malware doesn’t get talked about a lot, and that’s because it’s relatively uncommon compared to others, but it’s still just as dangerous. Crocodilus, a new Trojan on the Android platform, is one such example. Today, we want to cover how you can address this new variant and avoid contact with it.

When you travel, it’s crucial to remember that your digital security needs to be just as mobile and well-prepared as you are. The usual advice—such as creating and properly storing strong passwords and avoiding unsecured Wi-Fi without a VPN—are great tips that we share all the time, but today, keeping your personal and professional data secure is a little more complicated.  We’ve put together five security tips that are outside the norm to help you navigate your travels with confidence.
