No matter what type of organisation you may run, email is the front door. This is why email security is so critical. It’s where invoices arrive, contracts get signed off and where employees communicate about what needs to get done.
Of course, email is also where criminals get in. According to the Cybersecurity and Infrastructure Agency (CISA), over 90% of cyber attacks begin with a deceptive email.
Therefore, given how central email is to the effective running of your organisation/business, it’s worth asking who is providing the email security?
It’s never a good idea to treat security as an afterthought by bundling it into a broader IT contract. Looking after your email security requires working with a partner who thinks about nothing else.
The FBI’s Internet Crime Complaint Center (IC3) has been monitoring cybercrime losses across the world for a number of years and publishing the results. In 2025, they reported losses from internet crime in the United States amounting to $21 billion. This is a rise of 26% from the previous year.
Business Email Compromise (BEC) accounted for over $3 billion. This is a cyberattack strategy where criminals impersonate executives, suppliers or legal advisors to trick someone into moving money. Across the categories the FBI tracks, only investment fraud results in higher losses.
A similar picture emerges in the United Kingdom.
The government publishes a document every year called the “Cyber Security Breaches Survey”. This survey is produced jointly between the Department for Science, Innovation and Technology and the Home Office.
In the 2025/2026 survey, 43% of UK businesses experienced a cybersecurity breach or attack in the last 12 months. This equals approximately 612,000 firms.
In addition, phishing headed the list as the most common type of attack. Out of the group, 69% of the respondents rated phishing as the most disruptive type of incident to recover from.
Finally, Verizon, a global, corporate telecommunications company, publishes a yearly Data Breach Investigations Report. This report is now in its eighteenth year and draws on more than 22,000 analysed incidents.
Verizon found that email remains one of the leading routes malicious actors use to gain entry into an organisation. The findings also concluded that the majority of breaches contained some element of human behaviour and could not be put down exclusively to a technical failure.
Cybercriminals do not stand still. They’re constantly seeking new ways to compromise an organisation.
In the past, part of the job of detecting a suspect email was made easier by the poor spelling and awkward phrases that gave a hint of something not being right. In recent years, attackers have upped their game. Generative AI helps them impersonate your real colleagues with unsettling accuracy.
This is why you need specialist email security support.
Most IT providers are generalists by design.
They manage networks, keep servers patched, support hardware and software updates and handle many other responsibilities to keep their diverse client base happy. Email security runs the risk of being folded into this list of services rather than standing alone as a discipline in its own right.
A specialist managed email security provider, such as Topsec Cloud Solutions, focuses exclusively on email security. We eat, sleep and breathe how to keep our clients’ inboxes (and therefore data) safe 24/7. This focus shows up in several, practical ways:
We’re so used to seeing the big numbers that accompany cyber attacks that we can begin to think of these figures as abstract. In truth, they’re anything but. These numbers represent the real losses organisations have weathered. For some of those organisations the loss has been money, for others time, and for others the loss of trust of their customers.
These are not small losses nor are they easy to replace.
This is why email security is so critical to the sustainability and growth of your organisation. Email security requires deep expertise in the discipline, constant attention and a thorough understanding of how attackers think.
At Topsec, we’ve been focused exclusively on email security for 25 years.
