This will enable them to keep pace with your business’s changing IT requirements.
Experience – Check whether the MSP has experience in supporting businesses of the same size and industry as yours. This tells you that they’re familiar with supporting the technologies you use.
Service level agreement (SLA) – Make sure the MSP offers a competitive SLA. An SLA outlines the terms of their services, including response times, uptime guarantees, and coverage hours.
Communication – The MSP should communicate clearly and concisely without using technical jargon. They should also be responsive to your questions and concerns.
Third-party vendor partnerships – Ensure the MSP is partnered with the technology vendors (e.g., Microsoft, Oracle, Salesforce) whose products you use in your IT environment. The higher the partnership level, the more expertise the provider has to offer your business.
Financial stability – Technology plays a crucial role in the success of your business, so you need an MSP that can be with you in the long run. You can evaluate their stability by taking a look at their annual reports and financial statements. See how many clients they have and check their customer retention numbers.
Reputation – Read online reviews and testimonials of the MSP’s past and current clients. This will give you a good idea of what it’s like to work with the MSP.
Flexibility – Your business is constantly evolving, so you need an MSP that can change with you. They should be able to scale up or down their services according to your current needs.

Choosing an MSP is a big decision — but it doesn’t have to be a difficult one. By keeping these criteria in mind, you can narrow down your choices and find an MSP that’s a good fit for your business. To learn more about how an MSP can benefit your company, get in touch with us today.

A short guide to IT security lingo

Posted on July 29, 2022April 22, 2024 by Joseph Voldeck

As more and more businesses move their operations online, the need for robust cybersecurity measures has never been greater. However, many employees are still unfamiliar with many cybersecurity terms. Here are some of the most commonly used terms in IT security. By understanding these terms, you will be better equipped to protect your business from cyberattacks.

Malware

For a long time, the phrase “computer virus” was misused to refer to any type of attack that harmed computers and networks. The more appropriate term for these harmful programs and files is “malicious software,” or “malware.” Whereas a virus is a specific type of malware designed to replicate itself, any software created for the purpose of destroying or accessing networks and data with the intent to steal, corrupt, or encrypt these should be referred to as malware.

Ransomware

Don’t let all other cyberthreats ending in “-ware” confuse you; they are all just subcategories of malware. Currently, one of the most notorious of these is ransomware, which is malware that encrypts valuable data until a ransom is paid for the decryption key. In a ransomware attack, the victim organization may feel compelled to pay the ransom to regain access to their data.

Intrusion prevention system (IPS)

There are several ways to safeguard your network from malware, but an IPS is one of the nonnegotiables. An IPS sits behind your company’s firewall and monitors for suspicious and malicious activity that can be halted before it can exploit or take advantage of a known vulnerability.

Social engineering

Not all types of malware rely solely on fancy computer programming. Experts agree that the majority of attacks require some form of social engineering to succeed. Social engineering is the act of tricking people, rather than computers, into revealing sensitive or protected information. For some cybercriminals, it’s less tedious to convince a potential victim to give them the data they need than to create and deploy complicated software to obtain the same information.

Phishing

Phishing is a type of social engineering scheme that involves defrauding people using an app or a website that impersonates a trustworthy or often well-known business in an attempt to obtain confidential information. Just because you received an email that says it’s from the IRS doesn’t mean that it is. Don’t take such emails at face value — always verify the source, especially if the emails are requesting your sensitive data.

Antivirus

Antivirus software is often misunderstood as a way to comprehensively secure your computers and workstations. These applications are just one piece of the cybersecurity puzzle and can only scan the drives on which they are installed for signs of well-known malware variants.

Zero-day attacks

When a vulnerability is found within a piece of software, vendors will release an update to fix the gap in security. However, cyberattackers can release a piece of malware that exploits the security vulnerability before software developers can address it. This is known as a zero-day attack.

Patch

When software developers discover a security vulnerability in their programming, they usually release a small file to update and “patch” this gap. Patches are essential to keeping your network secure from the vultures lurking on the internet. By checking for and installing patches as soon as these become available, you keep your software protected from the latest malware.

Redundant data

When antivirus software, patches, and intrusion prevention fail to keep your information secure, there’s only one thing that will: quarantined off-site storage. Duplicating your data offline and storing it somewhere other than your business’s workspace ensures that even if your systems get infected with malware, you’re equipped with backups to keep your business running.

3 Types of hackers: What you need to know

Posted on June 20, 2022 by Joseph Voldeck

While there are many similarities among hackers, there are also some key differences among them. Some hackers want money for themselves and resort to evildoings, while others just want to make the world a better place. In this blog post, we will discuss the three main types of hackers and what you need to know about them.

A complicated history

In the 1950s, the term “hacker” was vaguely defined as someone who explored the details and limits of computer technology by testing them for a variety of purposes. But by the 1980s, when computers became more accessible, “hacker” became closely associated with teenagers who broke into government computer systems. These teens referred to themselves as hackers, perhaps because the word has an aggressive ring to it.

Believe it or not, several of those pioneering hackers now run multimillion-dollar cybersecurity consulting businesses, while countless others still run amok online, hoping to make a quick buck off of hapless victims.

3 Types of hackers

Knowing the history of hacking can give you a background on the different kinds of hackers, and this information can also help protect your business from cybersecurity threats. Let’s take a look at the three main types of hackers that can impact your organization.

“Black hat” hackers

Black hat hackers create programs and campaigns to commit all sorts of malicious acts. They’re what most non-IT people think of when the term hacker is mentioned.

Black hat hackers typically use hacking tools to attack websites and steal data. They may also create viruses or malware to damage computers and other devices. They commit crimes such as identity theft, credit card fraud, and extortion for their sole benefit, but they can also work for a corporation or a state and commit espionage and cyberterrorism.

Kevin Mitnick is a prime example of a black hat hacker. In the 1990s, Mitnick went on a two-and-half-year hacking spree, committing wire fraud and stealing millions of dollars of data from telecom companies and the US National Defense warning systems.

After spending five years in prison, he set up his eponymous cybersecurity firm and became its CEO and Chief White Hat Hacker.

“White hat” hackers

Sometimes referred to as ethical hackers or network security specialists, white hat hackers are considered the good guys. They use their hacking skills to find weaknesses in websites and systems to help fix these vulnerabilities so that they can’t be exploited by black hat hackers. Whether it’s selling what they find to hardware and software vendors in “bug bounty” programs or working as full-time technicians, white hat hackers are interested in making an honest buck.

Linus Torvalds is a great example of a white hat hacker. After years of experimenting with the Sinclair QDOS operating system, he released Linux, a secure open-source operating system. Linux is built to prevent malware, rootkits, and other computer pests from being installed onto your device and operated without your knowledge. This is because most infections are designed to target Windows computers and can’t cause any damage to the Linux OS.

“Gray hat” hackers

Gray hat hackers fall somewhere in between black hat and white hat hackers. Whether a gray hat hacker works as a security specialist or is a cybercriminal, the majority of their work is usually conducted over the internet.

While most gray hat hackers usually enjoy the anonymity that gives them the opportunities to try their hands at both white hat and black hat hacking, not all gray hat hackers live in the shadows. For example, Marcus Hutchins is a known gray hat hacker. He’s most famous for stopping the WannaCry ransomware by finding a “kill switch.”

However, Hutchins also created the Kronos banking malware. He was arrested in 2017 and pleaded guilty, accepting full responsibility for his mistakes. He now uses his talent by working for Kryptos Logic cybersecurity firm. According to Hutchins, he has since been using the same skills that he misused several years ago for “constructive purposes“.

The rapid evolution of the cyber realm means there is more information available online every day, and there are many sorts of hackers looking to misuse it. While the purpose behind each hacker’s action varies, the danger they pose to your data and company is constant.

If you think your website or data has been hacked, contact our cybersecurity experts as soon as possible. You can also contact us if you have any questions about how to secure sensitive business information.

Why two-factor and two-step authentication matter

Posted on April 26, 2022 by Joseph Voldeck

Two-factor authentication and two-step authentication are both vital for data security. But what’s the difference between them? Is one authentication process better than the other for your business? In this blog post, we will break down the differences between two-factor authentication and two-step authentication to help you decide which is more suitable for your needs.

According to the Allianz Ris k Barometer, businesses are more worried about cybersecurity threats compared to other business disruptions like supply chain issues, natural disasters, or even the COVID-19 pandemic. This is why business owners are ramping up data security measures. One way they do this is by implementing two-factor and two-step authentication. Many businesses use the two terms interchangeably, but these processes are quite different.

Two-factor authentication

Two-factor authentication (2FA) is a security measure used to ensure that people trying to access a system are who they say they are. 2FA requires users to provide two pieces of information before being granted access.

When you try to log in to a system that uses 2FA, you’ll be asked to provide not only your password but also another piece of information or form of identification. This second factor can be something you know, like a PIN or a security question, or something you have, like a physical token or key fob. If you have the correct password and the second piece of information, then you’ll be granted access to the system. Because of the additional authentication information required, hackers would have great difficulty breaking into a network using a 2FA system.

Two-step authentication

Two-step authentication (2SA) is an extra layer of security that can be added to your online accounts. 2SA requires you to enter both your password and a code that is sent to your phone or email before you can log in.

Adding 2SA to your online accounts can help protect your information from being hacked. Even if a hacker knows your username and password, they will still need the code that is sent to your phone or email before they can log in to your account.

There are a few different ways to set up 2SA. Some websites, like Google and Facebook, offer 2SA as an additional security measure that is especially useful when you or someone else is trying to log in using a new or different device. Others, like Dropbox and Twitter, require you to set up your authentication profile in the settings page before you can use their app. A 2SA setup is typically quick and easy, and only requires you to have your phone or email immediately accessible when you log in.

Which one is better?

Relying on a single-factor authentication process is no longer sufficient in ensuring the safety of your network. Securing the authentication process and making it difficult for cybercriminals to access your network should be on top of your priorities. Deciding whether to use two-step or two-factor authentication largely depends on your business’s specific security requirements. To take the stress out of choosing which between the two methods better suits your needs, call us today for expert cybersecurity advice.

Why managed IT services is best for SMB cybersecurity

Posted on March 14, 2022 by Joseph Voldeck

Without technology, businesses cannot compete and succeed. But with the advancement in technology comes the ever-constant threat of hackers and cybercriminals. That’s why small- and mid-sized businesses (SMBs) need to protect themselves with robust cybersecurity solutions managed by reputable managed IT services providers (MSPs).

The numbers

Through the years, the number of SMBs falling victim to cyberattacks has drastically increased. Ransomware attacks, misconfigured systems, credential stuffing, and social engineering are among the many cyberthreats that SMBs face. Also, according to Verizon’s 2021 Data Breach Investigations Report, one in every five data breach victims was an SMB. What’s more, only 47% of SMBs are able to detect breaches within days.

The financial consequences have also considerably increased. IBM’s Cost of a Data Breach Report 2021 shows that “data breach costs rose from USD 3.86 million to USD 4.24 million.”

The numbers don’t lie, so it’s only about time SMBs take cybersecurity seriously. You can safeguard your business from cyberattacks and provide a more secure customer experience by working with a trusted MSP.

Why managed services?

Partnering with MSPs is the most effective way to prevent attacks and defend against malicious threats. MSPs offer a full range of proactive IT support that focuses on advanced security, such as around-the-clock monitoring, data encryption and backup, real-time threat prevention and elimination, network and firewall protection, security awareness training, and more. Here are some of the services an MSP can offer:

- Around-the-clock monitoring – A cyberattack can happen at any moment. By having someone watching your networks and systems 24/7, MSPs ensure that any potential threats are identified and dealt with quickly.
- Data encryption and backup – Data encryption transforms readable data into an unreadable format. This can be done through the use of a key, which is only accessible to authorized users. This way, even if the data is compromised, it can’t be read without the key. Meanwhile, data backup is the process of creating and preserving copies of data so that it can be restored in the event of data loss.
- Real-time threat prevention and elimination – By using technology that can detect and stop threats as they happen, this security solution can minimize the impact of an attack and keep your business data safe.
- Network and firewall protection – Networks and firewalls create a barrier between the business network and the internet, securing confidential data, such as customer information, employee records, and trade secrets. Networks can be configured to allow certain types of traffic through while blocking others, so that only authorized users can access specific resources.
- Security awareness training – Now, more than ever, SMBs need to be aware of cybersecurity threats and how to protect themselves. MSPs can facilitate security awareness training that can help employees spot red flags and know what to do (and not do) to keep company data safe.

Managed IT services are designed to identify and fix weak spots in your IT infrastructure, enabling you to optimize the digital backbone of your business processes. With managed IT, you’ll also have faster network performance, a solid business continuity and disaster recovery strategy, and minimal downtime. You’ll also get a dedicated team of IT professionals ready to assist you with any technology-related problems. This is much more effective and budget-friendly than having in-house personnel juggling all of your business IT needs.

Being proactive when it comes to cybersecurity is the only way to protect what you’ve worked hard to build. If you’d like to know more about how managed services can benefit your business, just give us a call — we’re sure to help.

5 Wi-Fi issues and how to fix them

Posted on November 22, 2021February 17, 2024 by Joseph Voldeck

It’s difficult for businesses these days to operate without a good Wi-Fi connection. Having a fast, secure, and reliable connection enables quick response times and customer satisfaction. But what if your Wi-Fi refuses to work? Let’s take a look at five common Wi-Fi issues and how you can easily resolve them.

Range constraints

Wi-Fi works via radio waves that are typically broadcast from a device known as a router. To avoid a weak signal in your office, make sure that your router is placed in a centralized location and not hidden in the farthest corner of your facility. The Wi-Fi antennas must also be either in a fully horizontal or vertical position for optimal signal distribution.

Note that Wi-Fi range constraints can also be due to interference, so if your office is situated in a highly populated area, try changing your router’s channel.

Slow internet speed

Despite having high-speed or fiber optic internet, slow load times can still occur from time to time. To eliminate this, try the following:

Place your router in the same room as your computers.
Add more routers to better accommodate a high number of connected devices.
Limit the use of bandwidth-intensive applications and websites such as Skype, Dropbox, YouTube, and Facebook.
Disable your router’s power-saving mode.
Create a new router channel to avoid network bottlenecks.

Connection issues

It can be frustrating when the Wi-Fi network shows up on your device but you just can’t seem to connect to it. To solve this issue, try these fixes:

Determine whether your Wi-Fi connection or internet service is the problem. To do this, plug in an Ethernet cable directly to your laptop. If you get a connection, then the issue is on your end.
Reset your router. Use a paperclip or a pen to hold down the reset button for about 30 seconds.
Reboot your device.
Call your internet service provider if none of these fixes work.

Unstable connection

Random Wi-Fi connection drops can happen occasionally. If this is a constant nuisance in your office, try moving your router to a different spot or room. Avoid having multiple routers in the same location as well, as this can confuse your device.

Network not found

Your Wi-Fi network may not appear on your devices if your router is glitching. To fix this issue, try disconnecting the router from the power source and waiting at least 30 seconds before reconnecting it. You may also need to check how old your router is. If it’s more than three years old, then that may be what’s causing the connectivity problems. Replacing your router with a newer model should solve the issue.

Implementing these tips will help you avoid serious downtime caused by Wi-Fi issues. However, if you prefer to have a dedicated technology provider handle these for you, give us a call and we’ll be happy to help.
