3 Ways to Improve Your Company’s Security

Nowadays data and network security are more important than ever. It is more common than people think that their information could be available for sale online on the dark web. Email passwords, remote PC logins, bank details and other vital personal information. That’s why we take security so seriously here at Nostra. You don’t have to be an expert in network security to do your part and take the first few steps to protect your information. Just take the time to make these three rules a habit for yourself and your workplace and you’ve decreased the chance of a stranger obtaining personal information and greatly improving company security.


One of the most important elements of IT security are your passwords. The majority of people typically use the same or a similar password for everything. The password for your network, email, Gmail, Facebook, and Twitter are generally the same or similar. The challenge here is obviously the fact that if someone gains access to one password they will have access to all of your systems. Never use a general password. Pa55w0rd, Password123 or any generic passwords should be changed immediately. We recommend that all organisations introduce a 3 month password expiration policy at a minimum.

We also recommend that all passwords for all logins used should contain the following:

  • Both capital and small letters
  • Numbers
  • Symbols (X!”£$%^&*()~@:}?><,./;#’][)
  • Minimum of 8 characters


Every business should have a firewall, and there are no exceptions to this rule. The specific internal systems of your company will determine the necessary firewall type.

Some brands that Nostra recommend include:

  • SonicWALL
  • Cisco
  • Palo Alto

Nostra also recommend that a subscription is enabled to ensure that your firewall stays fully up to date. Most firewalls have an alerting system to report back on intrusion alerts. Nostra also have an alert monitoring service.

Further preventative measures that can be discussed with Nostra include:

  • Cloud Backup
  • Anti-Virus
  • Web Filter
  • Cloud Email
  • Web Proxy
  • 2nd Anti-Spam Engine
  • Group Policy

2 Factor Authentication

Two Factor Authentication, also known as 2FA, two step verification or TFA is an extra layer of security that is known as “multi factor authentication” that requires not only a password and username but also something that only, and only, that user has. Generally, this is access to a device that is not the one they are signing on to.

Multi-factor authentication (MFA) is a method of authentication that requires the use of more than one verification method and adds a second layer of security to user sign-ins and transactions. It works by requiring any two or more of the following verification methods:

  • A randomly generated pass code
  • A phone call
  • A smart card (virtual or physical)
  • A biometric device

By using this method of personal/network protection you’re personalising your security, taking a small step that makes a big difference. All, if not most, user sign-ins and transactions use this method now and there’s reason for it.

So call us today to see what methods above you have available and we will help you set them up as well as any other network options we can assist you with.

We transferred to Nostra for managing our network in October 2016 and immediately felt confident that our system would be brought up to the best possible standards of monitoring and maintenance.  We are happy that the latest in best practice guidelines are now in place and that our network is now on a fully stable footing.  Business continuity is obviously a key priority and they have put in place a robust system of replication and backups with a regular monitoring system.

The staff in Nostra know their IT and they have expertise in every aspect together with relationships with Microsoft and other key partners in the industry.  They manage everything IT for us apart from our core banking system and they have built a relationship with that provider also.

I am happy to recommend them as a strong network services provider

“Seamless, Efficient, and Hassle Free”

“We have worked with Nostra as our Technology Partner since 2011. During that time we have moved our mail to Microsoft O365, upgraded our servers, and deployed Microsoft Virtualisation. In tandem with Nostra we have reviewed and upgraded our Business Continuity Plan and have put disaster recovery failover in place. All of these initiatives have been accomplished in a seamless, efficient, and hassle free manner with no down time to the company. Nostra always conduct due diligence before any move and come up with business driven and cost effective solutions. They are very adept at providing the latest software solutions and advice with a customer centric focus.”

Office Manager

“I have more time to focus on my business”

“Although Nostra have committed to 30 minute support, the support engineers are usually online and fixing any issue within 5 or 10 minutes and we’re generally back up and running within the 30 minutes. They provide an excellent service and more importantly leave me with more time to focus on my business.

I would have no hesitation in recommending Nostra to any company who wish to cut IT costs without jeopardizing any service levels.”

Managing Director

“The Service We Receive is Unlike Any Other”

“We chose Nostra as our IT provider because they understand our business and give a proactive approach to managing our IT. They provide the fastest response time from any IT company in our market but much more than this they advise us on keeping our systems stable and our costs down.

They engage with our other vendors to ensure that once we make a call to Nostra any IT worry will be resolved.

The efficient running of our technology systems is crucial to the smooth running of our business. They have become a key IT manager to our business. From analysing our systems they have saved us a lot of money, we run more systems from less machines and we do so in a stable fashion. Our employees are an integral part of our business and our employees choose Nostra Systems.

The service we receive from Nostra Systems is unlike that given to us by any previous provider.”
