Cloud computing vs On-premise Firewall
Technology - February 14, 2022
Cloud adoption has prompted many vendors to move their attention away from
on-premises firewall solutions and offer cloud delivery models, thereby raising the
question,'Which is better for my business?”If you're unsure which choice is the most
safest, accessible, and economical, have a look at this comparison.
Let us look at Cloud in general. 'The cloud' has gained popularity in recent years,
and Gartner forecasts that worldwide end-user expenditure on public cloud services
would increase 18.4 percent to $304.9 billion in 2021, up from $257.5 billion in
2020. It's difficult to refute its merits, which include independence from hardware
limits, agility, and always-updated functionality. Nonetheless, the cloud vs.
on-premises software argument continues to rage. Let us dive into the comparison and
focus on the Firewall software
Cloud computing vs. on-premises
It's not surprising that cloud computing has gained such appeal, given its and
promise to offer organisations unprecedented flexibility, ranging from time and cost
savings to increased agility and scalability. On the other side, on-premises
software – placed on a business's servers and behind its network – was the sole
option for businesses for a long period and may continue to meet your business's
demands sufficiently. Additionally, on-premises apps are stable, secure, and provide
organisations with a level of control that cloud solutions sometimes lack. However,
many IT decision-makers believe that, in addition to on-premises and legacy systems,
they will need to use new cloud and SaaS apps to accomplish their business
Firewall safety: Is cloud computing
more secure than on-premises computing?
Cloud vs. on-premises security is a critical aspect ofin this discussion. Although
cloud security procedures have generally been looked upon as less strong than
on-premises controls, cloud computing is no longer a novel technology. Nowadays, an
increasing number of enterprises rely on the cloud to meet their security
A business that manages its own on-premises servers keeps greater control over
security. They are accountable for establishing acceptable user access regulations,
implementing firewalls and antivirus software, guaranteeing that security patches
are applied quickly, and defending against cyberattacks. This level of control,
though, can be a double-edged sword. For businesses with adequate IT assistance,
on-premises solutions provide assureance that their servers are secure—they are not
needed to entrust another organisation with their sensitive data. On the other side,
if on-prem servers are not maintained properly, they might expose a business to
On the other side, the cloud provider is responsible for data security. BeforePrior
to selecting a cloud service, it is critical to familiarise yourself with its
security standards. Is the data centre secure against intruders? Is software
maintained to include the most recent security patches? What safeguards are in place
to guard against hackers and natural disasters? The major cloud providers have
sophisticated security teams and adhere to stringent regulations. Nonetheless, since
they hold so much personal data, they are an alluring target for hackers.
Cloud security controls are especially dangerous for organisations operating in
highly regulated industries. Healthcare organisations must adhere to the Health
Insurance Portability and Accountability Act (HIPAA), academic institutions must
adhere to the Family Educational Rights and Privacy Act (FERPA), and businesses that
process credit card payments must adhere to the Payment Card Industry Data Security
Standard (PCI DSS). Enterprises that are subject to these requirements must
understand precisely how their data is safeguarded, which is challenging when data
is stored on the cloud. Nonetheless, an increasing number of cloud companies are
offering services that comply with these rules.
When an on-premises firewall is still
With cloud firewalls resolving so many issues, it's understandable why many IT
leaders are positive abouton the technology. Even the SASE framework highlights them
as a critical component–if not a must. So, does this mean that the on-
premises-based firewall is no longer viable and necessary? The answer is a
When it comes to large locations, IT administrators still prefer the dedicated
security appliance. This is because on-prem firewalls have a cheaper total cost of
ownership than cloud firewalls — at least for large organisations. Additionally, the
firewall's highly dedicated security ASICs enhance performance–providing a constant,
responsive user experience.
It's also worth mentioning that cloud-based management tools may be used to control
appliance firewalls. This reduces the IT team's responsibilities by facilitating
uniform policy administration. After all, cloud-managed firewall devices are
hardware, and so always incur a capital expenditure. Thus, for IT decision makers,
it is a matter of balancing advantages and costs in order to accomplish the desired
business goals. This balancing act explains why, when evaluating SASE systems, the
ability to mix and match cloud and on-prem firewalls is desirable.
Analyzing the advantages and
disadvantages of on-premises and cloud-based firewalls
Advantages of cloud-based software
Access from anywhere and at any time — You may access your applications from
any device at any time and from any location using a web browser..
Affordable — Cloud computing needs no upfront investment; instead, you make
monthly payments, converting it to an operational expenditure (OpEx). While the
monthly cost accumulates over time, maintenance and support are included,
eliminating the need for yearly contracts.
Cost predictability — Take advantage of regular monthly payments for software
licensces, updates, assistance, and daily backups.
Reliable IT that is worry-free — Since the Because cloud software is managed
for you, you no longer have to worry about maintaining the programme or the hardware
on which it runs.; Ccompliance and updates are managed by the cloud service
High levels of protection - Because data centres utilise security procedures
that are out of reach for most organisations, your data is frequently safer in the
cloud than on a server in your office.
Rapid deployment – Cloud-based software is distributed in a matter of hours
or days, in comparison to on-premises programsmes that require installation on a
physical server and on each system.
Scalability - Cloud solutions offer greater flexibility assince you only pay
for what you use and can quickly scale up or down in response to demand, for
example, by adding or removing licensces
Reduced energy expenditures — When you go to the cloud, you eliminate the
need to power and maintain on-premises servers. This greatly lowers your energy
Connectivity — To be productive with cloud products, you must have dependable
Costs in the long run – While cloud apps need a less initial investment, they can be
more expensive over the length of the system's lifecycle, raising the total cost of
Less customizable — While cloud software is often adaptable, depending on how it is
hosted, it may be incapable of supporting complicated development.
Total Ownership expenses - As you only pay once for user licensces, an
on-premises option may have a cheaper Total Cost of Ownership (TCO) than a cloud
Total command – You own all of your data, hardware, and software platforms.
You have complete control over the configuration, updates, and system modifications.
Uptime — With on-premises solutions, access to your software is not
contingent on internet connectivity or other external variables.
Capital expenditure — On-premises systems often need a sizable upfront
investment, implying that capital expenditure (CapEx) is frequently often necessary.
Additionally, you must factor in maintenance expenditures to assure continued
support and functionality enhancements.
Maintenance responsibilities — With an on-premises system, you are
responsible for server equipment / software upkeep, backup and recovery, and
archiving. This might be a problem for smaller businesses with limited financial and
On-premises systems take longer to complete owing to the time required to set up
servers and each individual computer/laptop.
Hybrid Cloud Computing Solutions
While the discussion about the merits of on-premises vs cloud computing is a
legitimate one, and one that many organisations are now discussing that there is
another option that combines the best of both worlds.
A hybrid cloud solution combines elements of many IT deployment paradigms, from
on-premises to private cloud to public cloud. A hHybrid cloud infrastructure
requires the presence of a public cloud platform from a reputable third-party
provider, a private cloud either on-premises or via a hosted private cloud provider,
and a reliable WAN connection between both environments.
Final thoughts: What is the best
course of action?
There is no one-size-fits-all solution to the cloud vs. on-premises software debate.
Each customer is unique and has unique requirements, which will impact the
deployment approach chosen. There are several things to consider before making a
definitive decision on cloud vs on-premises firewall software:
• CapEx vs. OpEx — Can you afford an on-premises solution's initial
• Backup and disaster recovery - Are you equipped with the tools necessary to
ensure maximum security?
• The upgrade cycle — Is access to the latest feature and compatibility
upgrades critical to you?
