For years, we’ve been told that “8 characters with a symbol” was safe.
This is no longer true.
According to the 2025 Hive Systems Password Table, a hacker using modern hardware can now crack an 8-character lowercase password in just 57 minutes.
Even with numbers and symbols added, short passwords are often broken in days.
The most effective defense today is length.
A password over 14 characters takes far longer to crack than a short one, regardless of how many special characters you add.
So what can you do?
The best option is to use passphrase passwords! You can easily make these for free with tools like BitWarden’s Passphrase Generator. Here’s an example of a great password that hackers would struggle to crack.
We use BitWarden passphrases for all our internal passwords as well as our client logins, so we know they work! BitWarden is a great password manager – not only does it create these long and hard to remember passwords, but it also stores them for you. Personal plans start free, and business plans are very affordable and scalable for small teams to big corporations.
If you need advice or help setting up cyber security for your business, big or small, we’re here to help!

- AI & Automation
Most organizations have realized that AI is not a sentient system looking to take over the world, but rather an invaluable tool. They have come to utilize it to improve their productivity and efficiency. AI solutions have been installed at an astounding rate. Some are used to automate repetitive tasks and to provide enriched data analysis on a previously unrealized level. While this can certainly boost productivity, it is also troubling from a data security, privacy, and cyber threat perspective. The crux of this conundrum is how the power of AI can be harnessed to remain competitive while eliminating cybersecurity risks.
The Rise of AI
AI is no longer just a tool for massive enterprises. It is a tool every organization can use. Cloud-based systems and machine learning APIs have become more affordable and necessary in the modern-day business climate for small and medium-sized businesses (SMBs).
- AI has become common in the following ways:
- Email and meeting scheduling
- Customer service automation
- Sales forecasting
- Document generation and summarization
- Invoice processing
- Data analytics
Cybersecurity threat detection AI tools help staff become more efficient, eliminating errors and helping make data-backed decisions. However, organizations need to take steps to limit cybersecurity issues.
AI Adoption Risks
An unfortunate side effect of increasing productivity through the use of AI-based tools is that it also expands the available attack surface for cyber attackers. Organizations must understand that implementing any new technology needs to be done with thoughtful consideration of how it might expose these various threats.
Data Leakage
order to operate, AI models need data. This can be sensitive customer data, financial information, or proprietary work products. If this information needs to be sent to third-party AI models, there must be a clear understanding of how and when this information will be used. In some cases, AI companies can store it, use it for training, or even leak this information for public consumption.
Shadow AI
Many employees use AI tools for their daily work. This might include generative platforms or online chatbots. Without proper vetting, these can cause compliance risks.
Overreliance and Automation Bias
Even when using AI tools, it is important for companies to continue their due diligence. Many users consider AI-generated content to always be accurate when, in fact, it is not. Relying on this information without checking it for accuracy can lead to poor decision-making.
Secure AI and Productivity
The steps necessary to secure potential security risks when utilizing AI tools are relatively straightforward.
Establish an AI Usage Policy
It is critical to set limits and guidelines for AI use prior to installing any AI tools. Be sure to define: · Approved AI tools and vendors · Acceptable use cases · Prohibited data types · Data retention practices Educate users regarding the importance of AI security practices and how to properly use the tools installed to minimize the risk associated with using AI tools.
Choose Enterprise-Grade AI Platforms
One way to secure AI platforms is by ensuring that they offer the following: · GDPR, HIPAA, or SOC 2 compliant · Data residency controls · Do not use customer data for training · Provide encryption for data at rest and in transit
Segment Sensitive Data Access
Adopting role-based access controls (RBAC) provides better restrictions on data access. It allows AI tools access to only specific types of information.
Monitor AI Usage
It is essential to monitor AI usage across the organization to understand what information is being accessed and how it is being utilized, including: · Which users are accessing which tools

If you use ESET on your computer, you’ve probably seen the big coloured bar across the top of the window: green, yellow, or red.
But what do those colours actually mean? And when is it time to give 4U Computer Solutions a call?
Here’s a simple guide to help you tell the difference between “all good” and “needs attention”.
When ESET is showing a green banner that says “You are protected”, you’re in good shape.
This means:
- ESET is installed and running properly
- Your virus definitions are up to date
- Real-time scanning is active in the background
- No urgent problems have been detected
You don’t need to do anything special when ESET is green. Just keep using your computer as normal and let it quietly do its job blocking threats in the background.
Tip: If you’re curious, you can still run a manual scan every now and then – especially before a big project or after plugging in a USB drive.
A yellow banner means ESET has spotted something that’s not quite right, but it’s usually not an emergency.
Common yellow warnings include:
- Overdue scan – It’s been a while since your last full computer scan.
- Outdated operating system – Windows or macOS updates are missing.
- Pending restart – Your computer needs a reboot to finish installing updates.
- License reminders – Your ESET license might be close to expiring.
- Minor configuration issue – A setting isn’t ideal, but you’re not completely unprotected.
What to do:
- Read the message on the yellow banner. ESET will normally tell you exactly what it’s unhappy about.
- Click the suggested action (for example, “Run scan”, “Restart computer”, or “See options”).
- If the yellow status doesn’t go away after you’ve followed the instructions – or you’re not sure what it’s asking for – give us a call and we’ll sort it.
Yellow is ESET’s way of saying: “You’re mostly safe, but something needs tidying up.”
A red banner is serious. It means there’s a problem that could leave your device, data, or business exposed.
A red ESET screen can be caused by:
- Expired license – Protection has stopped because the subscription has run out.
- Real-time protection disabled – ESET can’t actively scan files as you use them.
- Detected threat not resolved – Malware was found and still needs action.
- Failed updates – ESET can’t download the latest protection modules.
- Critical system issue – For example, some security components in Windows aren’t working correctly.
What to do immediately:
- Read the red message carefully. Look for buttons like “Fix issue”, “Restart device”, or “Clean threat”.
- If you’re unsure what to click, or the red warning keeps coming back, contact 4U Computer Solutions straight away.
- Avoid logging into internet banking, accessing confidential files, or plugging in USB drives until the issue is resolved.
Red doesn’t always mean you’ve been hacked – but it does mean your protection is not working as it should, so it’s best to treat it as urgent.
How to Quickly Check Your ESET Status
You don’t always have to open the full program to see what’s going on:
- On Windows, look for the ESET icon near the clock (bottom right).
- Green icon = protected
- Yellow icon = warning
- Red icon = problem
If it’s yellow or red, double-click the icon to open ESET and see the full message.
When in Doubt, Ask Us
Security alerts can look scary, and it’s not always obvious whether something is urgent or not. That’s where we come in.
If your ESET screen is:
- Green – relax, you’re protected.
- Yellow – try the suggested action; contact us if it doesn’t clear.
- Red – treat it as urgent and call us as soon as possible.
Our team at 4U Computer Solutions can remotely check your device, renew licenses, clean up infections, and make sure everything is running the way it should.
Whether it’s a simple restart or something more serious, we’re here to keep you protected.
