Unified Communications (UC) is the integration of various communication tools onto one platform to improve user experience and productivity. It is made up of three main components: voice calling, messaging, and web conferencing.

Unified communications integrates different communication channels and tools onto a centralised platform. This means that users do not need to switch between different communication channels as it can be done from a single interface, saving businesses both time and resources. If your UC system is provided under UCaaS (United Communication as a Service) model and the software components are hosted on a cloud, the UC system is managed and distributed by a provider.

A unified communications system offers several benefits, including improved collaboration, increased productivity, reduced communication silos, and enhanced flexibility. ARO’s approach ensures that clients and their employees experience a more efficient and integrated communication environment.

Unified Communications as a Service (UCaaS) is a cloud-based delivery model for unified communications solutions. It allows organisations to access UCaaS features on a flexible pay-as-you-go basis. Plus, the UCaaS infrastructure is maintained, owned, and operated by a service provider so organisations do not need to do this in-house. A UCaaS platform can provide collaboration tools, performance and usage reporting, enterprise telephony, and multitenancy communication data management.

UCaaS (Unified Communications as a Service) mainly focuses on integrating various communication tools and services to enhance internal collaboration within an organisation. CCaaS (Contact Center as a Service) is specifically tailored for customer interactions, providing tools and features to optimise customer service and engagement. ARO’s expertise in both areas can provide you with solutions for internal collaboration and customer communication needs.

Latest Insights

With the rise of remote and hybrid workers, more and more people are relying on their mobile devices to access and respond to work emails. While this may offer convenience and flexibility, it also comes with its own set of risks.

In this blog, we will explore the specific risks associated with navigating email on mobile devices and how to reduce those risks.

The Technological Risks of Email on Mobile Devices

As employees split their time between the office and home/remote locations, the use of personal mobile devices for work-related tasks, such as email communication, has become more common. Although this allows for increased productivity and connectivity, it also opens up new avenues for potential threats and security vulnerabilities.

Using devices for both personal and professional purposes blurs the line between personal and corporate information. This raises concerns about data leakage, as sensitive work-related information could be inadvertently shared outside the organisation. Plus, as employees are able to access company networks and sensitive information from various locations and devices, the attack surface for malicious actors increases significantly.

Additionally, personal devices may lack the same level of security controls and updates as company-provided devices, putting sensitive data at risk. Employees may unknowingly download malware or click on malicious links, compromising the security of their email accounts and potentially exposing corporate networks and data.

Rushed Replies, Small Screens and Email Blunders

Emailing on mobile devices often leads to rushed replies and the potential for communication blunders. The small screen sizes and limited keyboards dramatically increase the likelihood of typographical errors that result in the wrong information being shared. This could be anything from choosing the wrong recipient in a drop-down menu, attaching the wrong file, or accidentally selecting ‘reply all’. Although these are minor mistakes, the consequences can be severe.

Spear-phishing attacks in particular are a major risk when using mobile devices for email. As mobiles typically display the sender’s name rather than the entire email, it is more difficult to identify anomalies in the domain or subdomain. Plus, as many successful data breaches start from some type of spear-phishing attack, anything that increases the success rate of these attacks poses a serious threat to your business’ data security.

Emerging Mobile Threats in 2024

70% of UK office workers use mobile devices for work and continue to use multiple communication channels, including SMS. However, with employees using multiple communication channels, it is unsurprising that there has been a significant rise in multi-channel attacks.

After an initial phishing email sent to the victim, SMS was the third most common next step, accounting for 18.6% of multi-channel attacks. This is down to a few reasons. One being its high accessibility. Mobile numbers can be easily obtained through a wide availability of options such as out-of-office replies, open-source intelligence searches, and even email signatures, making it simple to target victims through SMS. Another reason is that mobile devices generally have lower security measures than desktop computers. SMS, in particular, lacks the robust security protocols needed to protect individuals against phishing attacks.

Balancing Convenience and Risk

Mobile devices enable employees to stay connected and respond to work emails regardless of their location, increasing flexibility and productivity. However, it is essential to strike a balance between convenience and risk management.

Issues such as small screens and increased vulnerability to spear-phishing attacks make mobile devices a potential weak link in an organisation’s security. To stay ahead of these threats, organisations should provide regular training and awareness programs to educate employees about the latest mobile security threats and best practices for staying safe while accessing email on their mobile devices. Plus, implementing intelligent email security tools can help further reduce these risks.

Egress Intelligent Email Security platform

One effective solution to mitigate the risks associated with navigating email on mobile devices is Egress’ Intelligent Email Security platform.

Integrating Microsoft 365 with Egress Defend and Egress Prevent offers robust protection against various email threats, including phishing attacks, data leakage, and accidental emailing to the wrong recipients. These models use advanced AI to detect threats and provide real-time alerts to users before a cyber attacks can occur.

Egress Defend uses pre-generative and zero-trust models, along with linguistic, contextual, and behavioural analysis to detect advanced inbound threats such as spear-phishing attempts. Additionally, Egress Prevent uses contextual machine learning and pre-trained deep neural networks to identify abnormal sending behaviour to stop emails and attachments from being sent to unauthorised recipients.

While using mobile devices for email navigation offers convenience and flexibility, it also exposes individuals and organisations to various risks. To mitigate these risks, it is essential to address both human and technological vulnerabilities, regularly update devices and applications, practice secure email habits, and consider utilising advanced email security platforms like Egress Intelligent Email Security.

In 2023, 347 cyber incidents were reported in the education and childcare sector in 2023 – an increase of 55% since 2022. Additionally, government data suggests that most schools and colleges have experienced a data breach in the past year alone.

Recently, The Billericay School in Essex suffered a data breach during the school holidays – a prime time for cyber criminals as IT support and security measures are reduced. In a letter to parents, head teacher Patrick Berry said the attack occurred even though they had “industry standard firewalls, firmware and malware security” in place. He also said “This attack has resulted in all of the school IT system being compromised and inaccessible by a complex encryption.”

In this blog we will discuss the different types of data breaches schools are vulnerable to and the solutions available to prevent them.

Cyber security in the Education Sector

Schools are particularly responsible for the data they hold, for safeguarding as well as GDPR reasons. Any information relating to pupils must be out of reach for any attackers and protected against any interference or manipulation. Plus, with the increased focus on digitalisation of the education sector, cyber security and reducing cybercrime in schools should be high up on the list for all education institutions. However, stretched school budgets limit how much schools can invest in cyber-security defences, with most of the budget being used for educational purposes. Fortunately, a DfE spokesperson said the government was increasing school funding to “the highest level ever in real terms per pupil, to support school leaders to meet their costs”.

Types of Data Breaches in Schools

According to IT Governance’s report, ransomware was the most common cause of data breaches among schools in 2022, accounting for 41% of all incidents. Another common cause of data breaches in schools is the accidental exposure of sensitive information due to misconfigured databases, unsecured servers, or human error. Other causes of data breaches include:

  • Phishing Attacks: Fraudulent emails or messages that trick staff and students into providing sensitive information or clicking on malicious links.
  • Malware: Malicious software installed on school networks or devices, leading to unauthorised access or data damage.
  • Unauthorised Access: Gaining access to systems or data without proper authorisation, often due to weak passwords or inadequate access controls.
  • DDoS Attacks (Distributed Denial of Service): Overloading a school’s network with traffic, causing disruptions and potentially masking other malicious activities.

Each of these breaches poses significant risks to the security and privacy of student and staff data, making it crucial for schools to implement robust cybersecurity measures.
